all right all right I'm not making a spot you will learn something rustling bleep eat we should order today you wanna treat different methods to make a song for you only one method Oh max evil okay pass the salt all right here I thought if you don't know who it is you have to know how to pass so under the plastic on the start you can cast it in terms of color you can casting in terms of hippie ability basalts now the tree you go to pass on because an i/o and cation paths so that's it okay so this is a very good summary what you can expect to spend three or maximum fall as an English actor subject New York who grass okay so first thing today you will learn number one definition of so the first thing everyone has to get what is definitions of sorts this again we are all right the salt in chemistry has nothing to do with the salt that we may be all right Kirby Scott in chemistry has no diagram relationship with a certain reality okay the salt that we are giving we call it table saw in chemistry called sodium okay but in chemistry's for only not only subjective or incorrect there are a lot more so what is top in chemistry stop in chemistry saw is actually ionic compound salt is an ionic compound but quick recap guys what is ionic compound something many people metal and nonmetal so is that I only compound that you form when I see when H+ ion in SD or as discussed I on whether H+ ion go to replace you change the H+ ion you change with Mentos if you can change it metal ion or another guy can change with animal me you ion there you get a song he's definition you can remember fantastic if you cannot forget about it it's okay yeah I know was I so much of memorizing - it's okay yeah so Smokies is the only compound before when H+ ion be active or passive or each month you change the response of the resting become a mental or alright okay okay give you three simple example guys this is the simplest and the most famous a sitcom I broke or ESD yet you know hydrochloric acid or H+ and Cl minus you change the H+ ion let's say with a metal ion over it let's add another coke or a serial number so your final product quotation all right this is okay alright y cosas they give me a 93 see I know nitric acid or H+ and no.3 - I changed a splash of the St I change it with a letter back to let's say sodium metal so I get something called sodium nitrate there is a song we're not to say this time must be a battle it also can be ammonium example this is hydrochloric acid which is H+ and Cl minus did you cheat each blocks with ammonia nominees and age for positive one so elated so what is a slot is the chemical compound they deform when you have st you take the issuance of an se up change the H+ with a mental or is it that's why why I teach you chapter seven previously because all most of the salt is made by taxi no second most of the stock make my exit so this is okay alright so now we will go on for there today we will learn two things I will focus on this book is bacteria so for today the first thing you all must know is sodomy this is the most importantly in this entire chapter if you don't even know solving with EU country in sauna so let's do it pain so that one of the objective at the end of the lesson is that you all must know solubility of the saw so you really of the stock means that you must know your spot dissolve in water or not yeah if you want to know the nitrate sodium potassium or ammonium comfort Ruby solid well example you see any people my friend you no matter the nitric is Nazi nitrate sodium nitrate medium nine three three nine three silver nitrate you don't care anything or nitrate compounds or people is okay simply anything or sodium so when you have sown in you don't carry the right sodium chloride you don't get a red sodium bromide you don't carry their Expo outside you don't get a wreck sodium hydroxide and evening doc sodium comforts so anything that got one of these for guide home for soluble you know need to have all of them you know you just need a have one of them is a weekly and each socks that have one of these substance okay so for rule number two you have to know something called su bah-ha is actually insoluble what it is by scuba come to here stand for sulfates soup stand for some pizza any people as performs a villa all right but stands of Bay Area a new substance resulted in formal car stand for cows here okay we have to be careful P is a shuttle for Pb Pb if you look in the Endicott plumb-bob even learning English record left and right so very real South a calcium sulfate left sulfate of them insulin so what a copper sulfate not here services of it not hear any honors event on here so you go here only these three softly are insoluble getting any other sulphate and it also here would be insoluble and said some of the school issue to memorize the DS P we see PVC some school according to one be is a hazard see Papagena be lumber or let be very real see is cow still clear all right do you see you can use any matter who's okay but later I'll tell you why me possibly I don't know Easter that I'll tell you one here okay why I know that is later yeah a rule number three rule number three is called Co hack mum Co Padma is insoluble again who is compatible ice-cold stand for all right Cole stand for chloride not only provide inclusive the siblings of proline diets the question is who are those sibling of chloride chloride if you check your everybody you don't grow seventy so groups that will need a pop from corals we have the brother coughed Romine apart from that you see her family younger brother Paul I can sell everything from route 17 yeah correct Roman era calls for an so o P is plumbum or we call and let Cora AG is called Stillwell and ER is called mercury which is not in our syllabus so let chloride silver chloride mercury chloride Emerson yeah all other chloride not listed here Solomon as an example zinc chloride not analysis for people okay alright sodium chloride not in the least so then only these three chloride are insoluble only these three software are insoluble is okay you have to be careful to that all right again some of the school while a small you member just that I tell you some fool us to memorize P inch p hv do you alright peeps them for lag is time for silver H is Hg stay for three and Zach no problem we pass on you defense whether you want to memorize in terms of the South one or you want a mattress in this way I will tell you my own reasoning why I do not remember ask for someone okay so if I can grasp our stuff to one is good better than nothing so I know there - wassup one I noticed the PVC I know disappeared I don't think it was not quite but the problem is that I go to remember that one I don't know which bus that one used for South Lake and which were used for correct understand I might call you sometime but even if I work for ya know Spanish food is something I know ready when I don't call I know this guy is folklore understand so my personal preferences I know you spaz aqua because although he's super soft or might have me to memorize but I don't know these two person who belongs in the South when he belongs to the crew I understand that's my that's my personal concern but like what I say if you use to memorize what is mascarpone and do you are doing where you are we have to stick with it yeah okay or if you have any kind of mathematical school that you can memorize is no I'm not cover here you here and you had another email before which works for you used to be fat yeah always stick that with your method it works for me understand alright don't have the wrong concept and tissue you must follow my one no such key you get idea we are just an option I guess sergeant that I use if you have home you use it even you you understand to origin about the kind of state meeting yeah okay that's what I'm one two three three rules really the name come on laughs what rule number four rule number four all the question who is cooler call all the stops Thunder react with acids you saw all this kind of seriously you see all them before to see the see that we have a basket is called calm morning the old all who really ask is called oxide the H really asking is called high drop style okay because you will not a c-plus communiques or water carbon dioxide okay oxide and hydroxide basis as it must be so anymore but it's okay so all the company or order hydroxyl all of them are insoluble yeah unless unless the Kahuna God so here unless properties here for ammonium they're different story it's okay ray like Z component is all about aluminum or a clean soluble sodium carbonate a box for here he's okay yeah this is P followed by the rules of Soviet if you can reach other all right so these are the core rules now okay that's what I said a lot of people even that here you can I am anytime again guys one of the c-plus and no brainer will you commit memorize you take a piece of people copies you that I said just like a piece of paper copies they needed a copy once in the day three for one or two weeks you have lost so much in memorize understand because seriously how we were friend you if you can't even but you are not going to yeah yeah you don't you know solovey do you want your ugly beautifully shut up for sure you must know Sony baby that's the first thing is entire chapter is over all right so this is our part one right part one the order about definitions of sod you have what is the meaning of what is the definition for part two you go to learn whether which salt is soluble in water which saw the game so this is the top one for today right so this is part one key so let's move on to part two so part two where we will focus 421 technical degree need three methods to make stops student problem safety don't know where and which method to use that's the problem this way guys as a chemistry student you must know how to do just a lack of your previous D when I get a question where I must go peace telekinesis for both X understand with the so different way so remember how you know these inequalities or both that sound check and email if the electroweak my true statement helium both carbon both copper both cantina both human is electrolysis if you're electrified by two different pieces of metal that easy for that cell understand it's something we done before that's right you all must know the structure way to thinking I got electrochemistry all I have to do this electrolysis for all that stuff yet I do accordingly same thing today the question asked me to make a prepare a song I repeat question for me to make a preparing a song so I need to know which are the best method to do so because there is remember it's okay so now under this you are flow chapters just learn a flow chart and you do about five to six sometimes together and only we move on to the technical portion so now the next thing you have to do is go they are all from three methods they are both the three methods for you want to make the salsa at all but remember not one not two not four is free it only tree they have three methods for you to make the sauce so what you should do okay whenever the question asks you to make a song please refer to this go time okay when ever okay we want to make a salt we all must be able to choose the right methods if you if if let's say you use the wrong factor no matter how lengthy is so answer is useless example okay this is an actually question they asked me to be the stop this unbelievable okay so it's at this an essay question is also cannot for example by right to make a song you should use if you don't the matter with you this commenter aid but you think the otherwise you go to use method B and your Deadpool you are very good we better be you write your whole page of food paper or it will be done nicely but I'll give end of the day you can type against you understand because you get all the metal we currently but the one memory right here so your method must be correct because if you use the wrong method there's no use here so you all must refer to this flowchart it always referred to this culture this culture and not even you you must you need to know okay all right again if you're having a problem and arise data piece of paper copy again whenever you want to make a slot axle start to rush it first question oh it's also sound is the spot if you want to make it soluble or not the first question always comes up is the spot that I want to make this all you were not there to answer there's no and there is yes okay because we must be insoluble also be worried if your sock is insoluble the method we use is called dipole the composition of innovator you correctly double the composition member it is included Dargo decompose now go decomposition method some of the book also called as per see p-paige purse deviation ended because you guys must know about what Percy Percy pygmies are very very small fine solids that's called perceivable sphere right so whenever we want to make a in so PeopleSoft that method uniquely use the need is called double decomposition where all you also can call percipitation care safe here all right miss unlike some of the capital to name one for example the order before when the walls courses also can call in the molecular force here you have to be registered a one guy's is the so if Leslie the spot you want to make this voluble you have also some another additional question which is does the spot God is the spot got the spine one c'mon guys reverse spark s cellphone Soviet the a is not a lot of people know so yes or no you have spa the method you use is called titration that you call it hydration method if the salt do not have spa if the softly known as ma you call it see reaction that the human evolved reaction also called neutralization that's it so there are three different methods that you can use here so your job for now is you shouldn't worry about them for now you just need to make sure that for what adverse what I gave you you need to know what method to bring back and I said that's good enough that's enough for now clear alright you must know your diagram your job can I give you two simple questions and I give you six pressure or sometimes okay that's why okay I'll give you two simple demonstration let's do two simple demonstration then I'll let me go do some self deaths yeah so here I'm going to give you a simple style test you you guys can try it on yourself okay so this now is how give you this this is the thoughts that I want to make all right all right so the first according to sink all right you just you just write these first we do together the second sauce it is so easy [Music] [Music] [Music] [Music] okay so now this is the petition I will demonstrate the first of June using what we learned today and the gnostics like you find you need to do this okay all right okay thanks first of all Z all right first question to ask yourself is this for the world think about variety called magma : let fluoride silver chloride and with three alright okay zinc is not in the least therefore CVC alright what you have sodium no I don't have Daisy no I don't have ammonia I won't interfere I should use acid reaction alcohol neutralization and said so the method I should use is for neutralization also call a steep reaction you will know why is the reaction in the alright next one second question barium something think about South Sioux Baja so in Sioux Baca I saw the bath where you will resolve it so it is insoluble so I mean I make a final good it if he saw people come here no need to go okay so the bantha I supposed to hear this called double become ball see yeah now I just go home yeah my double decomposition also not asked Bar C P alright guys gonna rescue you trying to do pressure to uni alright let's try right follow this flow chart as a game every time whenever you want to be the song goes out to question question number one is the song I want to make is on you but or not okay he's the soft spot or not right from there choose the right method you got it alright sodium nitrate no matter you look upon sodium nitrate is soluble because no horrible horrible this type of walk absolutely you before me boy all right second question we have spot yes the sodium so if you have soluble and sodium the master is supposed to use is all hydration it's okay next one magnesium nitrate same thing when he's a fighter has nitrate and it has nine free to be soluble so do we have stuck no sodium no putative no ammonia so you do a spa sorry for bad news 5 neutralization also known as reactions okay next one onion Carboni and we got company ar e soluble they all company are insoluble so when you come in for a well fine double it double decomposition or we call Percy P okay okay alright people go well this is a karate so you can either look and on the correct set of for disables okay what is here is the spot so anything of sodium police an onion compulsory well alright then you aspire here you have P the petition so soluble and spa hydration this is the method usually used in comedy second us iron ii sulfate look at south a deep about sovereignty supercar so onion is not in the list of Supercop therefore so you go then so when you are solving for the second question you have no spam you know sodium we have nobody's here we have no ammonium therefore neutral my last one cows here are united so look at are you not is a snippet of chloride think about correcting code Padma so let's see what and mercury is free time will be insoluble all right so calcium iodine is not in the least all soluble right sorry well so when you are soluble the next question you have spa no sodium no petition no ammonium so you are you don't respond so you should use neutralization okay so this is the three idea what you should do here so this is part 2 we read part 1 understand solubility that's amazing remedy now you understand why because always for people or more I give you these things I give you this culture even examples on universe pair if I gave you this you're not even here answer the first question you still don't even know who is unable to be seasonable today that's why the first and the most importantly distant I chapter is so VD yeah after MSS or maybe the second we learn about choosing the right methods to make a saw guys how many factor to mix off today so you all must know all right which one can use fear so the next thing what we're going to do is that okay we will use about one hour each to cover every matter which means I will I will spend about one hour the tissue dispenser what I would we should respect that one hour is resistant understand after human mystery method the shuttle finished 50% get this t-shirt to do not prepare and healthy so if you know how to prepare using all three mentor you already finish 50% area in Family Code which go on now I want every one of you to know exactly what is precipitation and this is worried water because you will know at this method very soon the gate in your home fire chatter fall for my chapter 4 you will add something called heat of mercy bigeastation okay for five chapter for heat of birth limitation at that time you will see the workers in division made clear all right so essentially at one stone you hit two birds that you know this work you have to so now I will teach you every single thing you need to know about Percy patient so missile cacnea I'll tell you what is precipitation so this calculation in the first method that was sunny blue is the one holiday season you need to know something called double decomposition if we could've BB composition or we also can call it as per see pee-pee shape because we see our manually per person with vision coming from the web purse EEP EEP EEP you keep on still made from now onward they will precipitate meteors are very very fine very small insoluble solid that is okay yeah he first of all so today you will learn in the one hour time frame you will learn from the hate to the pole you will not a to the Z body composition game so I don't have many requests I just looked at after one hour all right you fully understand what is the body composition here of course you need to exercise after one minute but after one I what I want you to know that idea what is the concept us appear to be there yeah that's we are so I will spend a lot of time to teach you concept this is so please listen to what Isaiah there are decompose should matter is the matter for us to prepare for us to make insoluble so so whenever you want to make me soluble salt the vector is actually for double decomposition second one I want you to know what is the idea look at the basic ideas also the basic idea is this when I say double the composition you need to do is you need to take a soluble so many people solving Assad meets with another sword in Warsaw so when two syllables of mix together they will have a process atomic exchange partner they will exchange their partner after they exchange their partner you will end up with insoluble so you will end up with and neither soluble so this is the most important concept you must go for the body composition okay I'll give you a simple idea so that you can imagine a bit better than we do Gallipoli points applause yeah so so it was for me a very quick so is he usually you have the liquid it is a liquid I call it a story or soft number one this is a solvable song this is another cop this is also be quick this is another song okay so you have two solvable sort you mix together so you pour down and you mix together us so we mix together these two soluble so would change your partner efficient so after cheeseburger you always eat two layers you are obviously to be here why one day year is the insoluble salt dice well as it is on you is that these guys are stormy normally Sonic is denser so that falling on this thing at the bottom so the bottom here is the easy solid rock okay apart from that interchange further you also get a soluble socks only Wasabi's the liquids so the liquid will flow on top gear's okay all right so this is what you need to know so when I sit down body composition just imagine I take two liquids I mix these two liquid together after mix these two liquid this tool if we will change the Aparna inside I'll tell you how we change later after cheater partner you will see to layer the top layer here is a liquid which is the solid mossad the bottom plate is a solid which is the insoluble so it's okay this particular process is called double the components you should get it so you get a picture of us so later we will do some technical example okay all contra is no tree example I do - you do whatever we try to do tree example I will do for you you will do one for me thank that's it alright so today I just hang out without the compost we know you want - ready - you can take it - lugia everyone here first example we said California first example of course you might feel a bit blood wait by this dream up okay hang on there just get some picture of us let me do another example afterward if after example one into you if you were a blur just ask me he's okay yeah so example who are very important please stay focused and listen and so this is what happened here alright so the question is the question asks us to outline the matter in order to prepare us all these sort is called black to sow if this is the question this question come he asked to be as safe and we are talking about seven to ten months and months if this is the real question keep my SPM 2006 okay apply the method to prepare that you saw paid the maps even to you is Stella box no worry don't be panic just follow the flow okay so this is my simple strategy go back to the flow chart go back in the flow chart in order to design your map just that what we what we let previously so my coach at the first one left do something about that - some exact lack to Southie so think about South it is super hot so the South vacant or let let's outfit pure ethically is instrument so when we know the net to Suffolk is insoluble I know the matter we should use double decomposition so we only can use double decomposition method the other method cannot be cost double decomposition is the method for you to be philosophies of it they ran so any one of you here don't understand why I use double decomposition to make that consulting wait let do something is an insole it was also we have to use the body composition so please be reminded once again our second factors now when I give you and he thought movement is not even to you in the form of a mainly over the song even to you in a photo formula you must go to also subject to question soluble or not God spa from there you choose your method yeah okay now we have make our choice which is double decomposition so I say just now what is double decomposition soluble soluble change partner insoluble and soluble so we design so we need to take us on it well sauce mix with another store info thoughts is that so we would change partner is to from you change what I'll tell you how they changed either nothing to worry at now they will change the Parnell after they treat your partner you will get that eats on equal start if you wonder and also you have another site for that a Saudi will solve it you know one at issue on that you know where we have one by one okay let's stop okay question won't tell us what are the Saudi will solve their we they won't tell us they will be that kind so you all must have some skills to predict it you all must know how pretty and choose the right song reverse of the user it's a big technical example one can be very confused but please hang on that recently worked right over yeah all right so why do we do something most are you want to make lactose outrage so one of the so do so would be futile and this one equals R will give you that one of the soluble so if you and the facts out yeah all right I offer you the let you offer me this outfit that's why talking together become less healthy make sense or not now please okay so who is the sonic Assad that connect who is the sole inverse of that connect dysentery all the salt no matter sorry beliefs are above all our resort they have ions because we compact definition salt is an ionic compound a forma when H+ ion in a secret base with methyl or ammonium the definition if you remember never mind you just need to know all the salt always for your I always my charge alright soon okay here so always have to charge plus and minus I so let make a gas that what is a trusty VD 2 plus version also I know the leg is the PB to mass which means that already know who is the owner of the varsity variety but I thought I need to make a guess who is a negative so I need to choose an acne I have to put here to pairing with the legs alright so but we are so very negative on out there you cannot simply CPC officer party and the oxide i put upside here and on why because you can also be so hungry sleepy put an agony ion because again already you want it to be solid well you get here alright so how to make sure that you can make it solid well so we go back to the rules we'll just now if you remember no spa is all soluble everything of no smartphone from sorry but no is nitrate and all 391 as is sodium + 8 + P is potassium K + is ammonium nh4 plus so these four I don't have always soluble so please just play with them is okay so you know you need a negative ion which is all involve ID my toss is fear despair e93 understand just recognize it with you so you just pair with nitrate so you already know the first thought it was for the first raw material you need is called black nitrate understand each other that's how we do they have a pretty how you predict the formula for for chapter 3 when a really - I on the charge are different but no cross here cross right so you do that cross member so your soluble spot is actually so your sodium per spot actually if this gaya so you're solving power saw I read somewhere I love the nitrate on that nitrate this is your it's okay today because pv2 wasn't an Aussie - where the chachi if it is to the cross method is okay you guys understand I get it good so I know my first raw material which is great so let's go for a second money now I'm looking for another raw material this raw material has to be a solid Musa and this raw material must be solving safety I know all the smoke masks have plus and minus and I know the softness of Southwick and I know sulfate is so4 - am i right I know the sulphate must be a slow go to - so I know that equity ion has to be solving but I don't know what is the most it is the question of Deltora so now as usual you are the one who making a decision now so you have to make a decision to choose a positive are you to put here get it but again there are so many positive ion out there you cannot simply simply choose because you want to make sure is yeah so if you want something for you but please don't the new microscope or the note spa so you want a positive ion please don't use nitrate nitrate is an entity understand so you can just sodium you can choose potassium you can choose onion either one is okay let's say I chose sodium so I put sodium here so I let the sodium thiosulfate simply form for chapter 3 so the transition in glass as operations to miners will introduce different Duda cross so you will get the formula called and a through s4 for sodium sulphate Pia so you already figured out what are the raw material maybe this question yeah the first format here called net nitrate the second row material called sodium stop it is okay now let's get it done alright so we know that we have to solve most of they would change fund of Argentina change partners Oh chicks when I left change partner wait something okay so the blast will take this other than - so that come up with something that sounded pbso4 okay then the sodium Perry with the nitrate so the sodium Perry with a nitrate so you form sodium nitrate you get at each other can you see at the end of the day you already make the lets out there you wonder you can't each other here please begins with this equation but is so important because when you write a chemical equation you know what he's doing what is happening yeah and don't forget I can be the equation Oh easy to balance up so one leg on the land one leg on the right to nitrate on the left one nitric on the right so you have two years on a more effective sodium or two which is great yeah sorry has overall good here for now please make sure you know how to choose this method and how I write this equation is okay which is where very very important and if I knew something technical head now but trust me this is most important is that when you notice that the rest is easy in the job all right so let the opera summary for you are so this is the first part it's okay right you guys can dig know on these and talk about this everything necessary then we do one more example together here they're only a tissue what to do next of course expect write an equation when you several not expect that yeah we not done yet there are some form of Ebola later here for now this right is equation was fun they meet continually and finishing Beasley all right they just don't expect this chemical equation will I give several maps and I said no way all right this is an essay question you must write a good description appear in a visa carefully a lot of people's the problem initially is that always complain so it's very hard to shut up because I need to memorize many things well I can't deny that you need to memorize but I don't go you don't need to press here and you can memorize in a smart way of tissue babies and memorize the smart way I want you to memorize die right memorized picture don't memorize words or paragraph is hot yeah and many things can be made using my colon what I very common sense I tell you what it make common sense to be here alright so this is the strategy to do salsa everyone here I give you a strategy and we finish it so if we want to solve the start the strategy these days number one you are go to choose the right method I want you to choose the right material or so-called reactant and choose the right reactor also call raw material after you choose the raw material which is what you need you all go on with right in a good chemical equation which you also did right now we have to wanting to go after a chemical equation I want you to draw a diagram draw a picture okay then after that I brand and only you turn it into some words turn into some words description this is the initiative magnetism on how to begin all right guys you can use that state I understand in how to advertise we have left nitrate we know that nitrate so leave us off so he was not means liquid guys saw only got two states be insoluble in steal the Queen's if that is horrible you saw sorry here so I have a sore knee masala movie called that nitrate so it's a liquid so you have the beginning guys [Music] okay okay the sentence only will sort is called sodium sulfate so sorry miss or you don't another comeback weeks so Soviet something sodium any 2s so everyone understand why you were together because I got two soluble salts so you must of these naga two liquids okay so now that you want the to liquid to react what you do in SH you mix them together so you just mix this means normally guys in chemistry after you mix up after you mix boundary condition everyone will ensure that baby's probably don't do this for action you sir okay you use a glass for study understand yeah alright so you mix and stuff to ensure the mix perfectly is okay so after you mix and stir you know they change but now the picture won't show how to change - oh we don't care after change partner what you get is so important soluble one more time guys movies solids so he will be liquids so slowly and equal you expert you see two layers at the same so you will see two liters of this is number one so the second diagram you expect to see Tullius like this remember the water layer will be the solving which is the insoluble star so hope you Father may you be in for me who is it you'll be sort of a guy lacks out become it lets up in Sumatra insoluble so you gather peacefully well that's often water on top here you have a solemn of Allah so the soluble father who is it refer to the equation sodium nitrate so you already have sodium nitrate here alright you know so you already found two layer but guys allow you ask you a simple question in this particular question your concern your main purpose is what you want to make one lakh somewhere yeah so do you get the next topic you want to really yeah I already get an estimate I'm quite the but the last of it comes along with and then aside for that sodium nitrate I don't want here so we say I want the one box out on that balcony give me another one for free bonus which I don't one free bonus here so now I must think of the way to stack up here so in a common sense we know in Saudi movies solid soluble is liquid slowly and it will normally you know left how you separate them how you separate a solid and liquid you know that normally you need to agree operating through complicated super simple thing just via solving and liquid just would do the job as I do just buta all right make sense right guy see when it through filter you drove in the favela is a beautiful when a few you know on top here these are an insoluble stop which is lack of stopping and here you know this is a soluble who is a sodium 93 good night can you see you already separate up to rock guys the question that I want to separate down I don't want the solid nitrogen ah okay before I go on this is the steeple that concept used you carry a lot from nothing on the floor next real accident Lavinia this is a very important Kosovo a in SPM all the sort that we meet them in SPM or the spot that we meet must fulfill three requirement number one they must be a solid you must make a solid saw number two or a spot we may be SPM must be clean now the tree or the stopping maybe SP air must be dry he's okay so you know so far all right according to what you don't really need have you gotten the Sony thought yeah the next outfit that I want is already solid okay all right is it clean no because even of the filter the max you have some sodium nitrate sticking with the less helping you get idea even after people you can't deny that you might see you have some of the sodium nitrate liquid sticky along with the solid pure so how are you going to really clean the one and only way to free these days huh you get something you get a bottle of this view water just flush this market you should be still water just press the clock let the water run through when a water right through you wash and clean up solving so now you're solid completely understand lastly last be how you tried it everyone listen carefully because you are using it the one and only way to dry the salt in bass we have the one and only way to drive a sock in SPF is take two piece of filter paper you take not necessary to piece and it cools back also them but if they pull through the paper you will take the filter paper you will put on the sole in here this is the solid this is the let's outfits only you put in a middle and you just perform the compression you compress you just press so when you press the Sami you would actually have to try understand you are not allowed to use some funny funny people right and I said I saw last I go people say put the subway under the fan for hours what common sense it works but is not acceptable here in SPM only allowed one member which is compression [Music] just leave some use too much common sense Oh put the legs out in five minutes while theoretically nothing wrong Curie Weiss is okay but too bad answer is acceptable you can reach other there's only one way to kind of compress so how do you remember picture don't memorize the words why now you see the magic after you remember or picture you just use all these features the writer who works cut or mystical do-overs which I will do now you can see on how I make hoping here we have [Music] you wake up okay and neither because if you come another beaker with another solution which is hot sodium sodium sulfate solution is okay so you've already filled up both right what to do as you can see here you mix okay so you just meets both solutions you have to so you should mix them together after weeks you go upon upon mixing you call the new thing called mixture we call it mixture so you think you've coated whole thing for mixture exam so can you see my first three things already explained the first diagram is okay all right now what is he two layers this format all right you must be two layers come on okay so after you get to the year but you don't need to expect the top layer is what both debris is why don't you go to X then I said after this one happened after come to later you go to filter what is the purpose of Utah I wanna get it right who says la vida laughs subway yeah alright so he just is so I just the mixture so why I think that Alicia I do because I want to pay I want to get laughs full south way okay let do something you can use that what Solly if you don't want to render what's on it you can write in sodium will start or you can use another one of your tall per CPD and you view the deficient we're perceiving it precipitate with the insoluble salt in it so after they will you already get the info rubles of you one is okay we're not from the picture or as Julia you watch it here you use the word watch you can use the word flash you can use the word reasons or okay you watch flash or you rinse the precipitate also called a left use effective flash it may be still or it must be this in water we can detect water because hot water are not clean clear alright the cleanest water inlet is the water aftermath fantastic you've already had a clean saw ultimately why am i driving so you just dry the stock or try the precipitate how you do it came by Pressey between filter papers in between so you use the filter papers you compress are you do that by doing this you get stubborn us understand each other not easy but not too hard yeah that's why don't memorize this diverse that is happy you memorize these guys memorize picture if you have this picture in your mind all these services that we create yeah that's why I don't memorize words because words are to memorize if you can memorize picture you can imagine what is happening is much easier time so listen to my advice whenever they ask you to make a song whenever they ask you to make a song no matter what method you choose to be no matter you use double decomposition you use neutralization or you use titration whenever you want a bigger saw order the question never pension please please and please write the equation this equation down and saw the equation you wrote on the first point some time ago the last point you don't care first or last doesn't matter the sequel never mind as long as the equation should be there understand why when you write these chemical equation you somehow proof to the next Amina that you know what is going on clear so please don't forget in space already you just dump in your chemical equation is an equation just is OK by doing this you should able to get good marks if you don't each other know very hot but it's all about how you do need a very systematic manner are you doing that now let's go together to see where what's the possible number why whenever we want to make a sauce first of all you must use the vector how is you Samantha the flow child a source of the true question is the soluble do you have a spot from there choose the matter out of the tree and people or raw material or the our body composition what is the raw material so you must know mimosa change factor here so your raw material is to Saudi bizarre you use the way I taught you just come to figure out who are the two so people saw the first ornaments or must give you done that the second for me was of a few de Southie yeah after you part of your raw material you write a good equation which is somewhere here after you write an equation you know exactly who is reacting then you come to do a simple stretching of a diagram like this after you have all this picture you change all this picture in a written story you can teach other this is what you should do alright again guys is not easy but it's no harder is no harder you just need to make sure you can do the systematic manner here it again you have to practice here no way you just look at to example I have on a white pot here without doing anything yourself you wanna set no appear you have to really believe in effort trust me if you truly understand into example here if they initiated go to find two or three similar question at least you do no sound is enough very clear all right let's see Soha okay you wanna see what happening here we do one okay we do want to get it out one more right so now in any one for example let's do it this morning ammonia example number two this is the last example we learn example number two we all need to outline a vector to make a guy this guy let's say we call a mask this I call this guy called magnesium ha baloney all right we want to make a salt called magnesium family all right as usual I want you to follow all my strategy together that's the strategy so if you want to make basalts first and foremost you can refer to the flow chart as shown over here you must choose the method you choose the method also self permissive company X or Nevada in story well because all companies are evil evil ruler of Odessa rule number four all casual did not is Oliver so you know magnesium carbonate is insoluble so when you wanted to beta if so he goes off there's only one method applicable so you all have to use double decomposition I call it the Dilla decomposition are you okay now I already know the song I want to be insoluble sod and I already know that matter I suppose uses double decomposition now let's get done so the next thing is that we all have to choose the right chemical over all bacteria what is the raw material for our decomposition now X what is that important cause that will attest antibody composition is so nimble sword plus another so when tucson universal fits together we will exchange partner so when to so Universal go and they change the partner you are getting the insoluble so that you wonder and also another side product soluble socket you know one is okay for me this is the most important steps that's great so now why you need to sorry for saw the first Oliver Scott must give me magnesium the status or reverse table has to give me carbo names all right one keeping medicine one giving carbonate join together recently and then so let's go and make the gas again so I know all the salt no man is forgiven or not I have plus and minus so the plus I know this magnesium because the reason is mg 2 plus so what I know the class is magnesium same thing I need to choose a negative ion to attach with it I have so many that me I am now there again I can simply chose because we need to be strong about the press are you pal next week I will look over the book it's nice rate and over 390 MRI so you carry with no.3 negative so you know the first raw material is called magnesium nitrate so do not cross matter the to come to here the one come to here mg 1 and O 3 2 so your first moment is magnesium I'm trip so I am right now so this is hawala mg and o3 to everyone understand wanted to decide okay yeah right this one I mean another one more raw material this problem here is a solving the saw and consists Calgary and I know saw have plus and minus Connie I know this negative is co tree Oh - understand so I already know who is the negative fella so I need to find a cause I put here the positive ion must be solving for one the best for me but positive ion is spa sodium potassium or ammonium let's say I use potassium here hey sunset City you can see the charges different to the cross method one come here who come here k to see all three so you have K to so now you guys already found out the torment you know you needed what is magnesium nitrate one is potassium sulfate you hopefully found the right moment you do it now the next thing is that you must complete the equation to complete equation you need to let them change model so magnesium will go abroad Republican Carboni you get magnesium carbonate which is what you want to do here and another Sakura the potassium - with nitric you will get potassium nitrate please be reminded all your chemical equations must be balanced so I put two here okay so now you already come up with a good chemical equation so after you come up with a good chemical equation you can continue with drawing a good picture so your picture okay so you have to sort it also means that you have two liquids the first liquid called magnesium matrix or changing so this time become magnesium nitrate the second degree is called potassium carbonate changing so you have what is the comunidad so we have two liquids because they are two solving bizarre so you mix that stuff as usual after mix and stir remember double decomposition will change partner will change partner you get insoluble and soluble you are getting a solid and a liquid so as usual we form two linear understand so you must be careful who is for a girl who is nice or you know so we know that in some remover is magnesium carbonate so that is for ammonia water so the water is magnesium carbonate one is the soluble easier nitrate are you mean so your reform to lay here again your main constant is only done magnesium carbonate you want to solve it me right so you have solid and liquid be sure so it's time to either if you draw just filter the both the top should be the solid you wonder which is magnesium have worry the water is something that you don't want which is the aphasia I'm straight so after filter you've already catastrophe why allow me to remind one last time for today the slope we begin SP air must be clean try and solve it you already have the solid saw because this is all because God is throwing us off must be solid you already have a solid saw yeah because your mechanisms operate by seems to keep with some decent microphone here order if you thought he was half of this energy facility so you said is they want to flash or briefs water right through so now you may be said company will be very clean must be dry only with the only one way to try the stock is compressor so put a salt if you want to drive adhesive company put the medicine coming in between through the papers and then you just okay so here you can use very simple just a machine to Atsumi the first one year between is your solution instead of me let my click down and become magnesium nitrate the second one is that here you use potassium carbonate change this one become more patient okay the rest all can be the same same same same same only a different filter the make sure to get the left to something in this case the sauna solving questions do we have to write a warning of the solution if you know what is the volume you're right if you don't know you don't okay so what is the motive in most attacks when they release an activated in some of the text or some electrons additional warning if you know the morning you should write not only rewarding and concentration if you know you should write even don't know you need but I issue a simple we if you want to write issue you just be allowed gas depends on the container in calcium to container in general of big and small but a big container I like become conical flask those are big container small container it has to so when you have a big container like these days which is gonna become your warning we can play around 50 to 250 200 let's say I mean a simple answer if you have a week I had one India I had 100 cm q okay what about a concentration concentration you can use any concentration you want starting from zero when 0 1 all the way to 1.0 if you want to be hassle-free just use 1.0 / dnq is okay but this is purely optional understand you get idea right e SPN maybe you don't write these you are fine actually right so if you know about the word and concentration be right if you do know it's okay yeah it's a good question again so you realize the top of the company marina here picture is all about how we do in a strategic manner if you ask me advice what is the most important thing here is actually how to choose the right chemical for me the most important that is choosing the camping to end right in the equation these two are the most important date so many people will fail to write the equations why because they would memorize if you memorize this fact because that what I say if you memorize lets out wait in your textbook but exempt or is other change of Magnusson Carboni you cannot be flexible now to change get it but if you understand the reason you know exactly why we doing this and that can be much easier for you it's okay this chapter is quite tough but it's not as hot as you appear you just need to have the wear restructure way and a very good strategy is okay so any questions you want to ask before you end up with a lesson okay and guys the best way to maximize revenue enough or not is go back and try some questions okay go back and try some question for me Damascus the sat-7 to cannabis quite common is okay so when you get a question please answer sell all the spots they asked us to make is this for you or not is it was far from that choose the right methods so the line for example for today we only let down low decomposition so when I know that man that I should use this quarter body composition I think what I must know about that body composition it soluble soluble change Magnum insoluble soluble so I need to figure out the true sodium install understand so why am I to Solomon saw once the reverse of give me the hate that I wanted one so numerous of in detail who is the head it is a calculate the hippies magnesium the film is carbonate yeah so you must know Pam easier is the for sleep I want to miss Oliver Cameron I trip today Carmona is a negative ion to make it soluble parents spot sodium potassium or ammonium here after that a completely situation and change the condom once you accomplish this equation please go and draw a good library because when you draw a good diagram you somehow people imagine what is going on here and we this also be irresponsible over it some people but you can use this diagram to goreng your answer yeah because all these thing is just that you look at the spot River and there are different in mind just that was falling from the picture man your idea is very hard that's why you don't go to memorize these misleading people who mean so it's not why I need to memorize sevens that memorize a verse that you memorize picture here I can memorize picture in the easy way alright so I think that's all for today it right in next lesson in next lesson which is on the next coming Tuesday we will actually cover the second and it's okay alright so a boy is fine don't bad try some exercises on this time to be composition you having any problem just absolutely in excess it okay alright
