in Section four point three will be discussing about electrolytes and on electrolytes so what are electrolytes electrolytes are compounds that produce ions and therefore can conduct electricity when dissolve in water water is the solvent use here and because the solvent is water the resultant solution is called aqueous solution electrolytes can be broadly categorized into two groups strong electrolytes and weak electrolytes so strong electrolytes can ionize completely in aqueous solution and from your secondary school days you already know many examples of strong electrolytes for example sodium chloride right so sodium chloride when you introduce this compound into water they were ionized completely to form the sodium ions and the chloride ions and what are we electrolytes with electrolytes ionized partially only in aqueous solution for example at the no weak acid better knowing as it is a weak electrolyte right so when you introduce after knowing acid into water some of the ethanoic acid molecules will be dissociate or ionize to form the protons h+ and the after knowing ion the remaining part of ethanoic acid will remain in the undissociated molecular form okay this is a pictorial form of what we have just discussed all right so you see three different examples sodium chloride potassium sulfate are examples of strong electrolytes both of these compounds ionize completely to form the respective ions and they can conduct electricity or there is complete ionization these two compounds and therefore they are strong electrolytes as mentioned earlier on ethanol as it is a weak electrolyte because there's only partial ionization into the respective protons and ethanol ions so from electrolytes we move on to non-electrolytes what are non-electrolytes non electrolytes are compounds that do not produce ions and therefore do not conduct electricity when dissolve in water right so most molecular compounds are non electrolytes for example glucose right so glucose when D is off in water they do not produce ions and therefore cannot conduct electricity because the glucose molecules will remain in the molecular form another quick example of a non electrolyte is better not again some pictorial form to illustrate a non electrolyte as you recall earlier on sodium chloride is a strong electrolyte because sodium chloride ionizes completely to form the respective ions and can conduct electricity glucose is a non electrolyte because when it is off in water no ions are formed and also cannot conduct electricity okay in this light we have summarized nicely for you the different examples of non electrolytes and electrolytes so what are the examples of non electrolytes they are all the molecular compounds except a six and basis as you learn earlier on electrolytes can be grouped into strong and weak electrolytes what are the examples of strong electrolytes they are all the ionic compounds they are strong acids and their strong basis and we electrolytes they are the weak acids and weak bases so in this light we show you the various examples of strong acids strong bases weak acids and weak bases so what are the strong acids you have nitric acid sulfuric acid HCL all four perchloric acid HCL all three chloric acid and also of course HCL hbr h i-- hydrochloric acid hydrobromic hydroiodic acid so these are the strong acids that you need to know and strong bases were at a strong basis typically they are hydroxides from group 1 and group 2 of the periodic table for example from group 1 you have lithium hydroxide sodium hydroxide potassium hydroxide and from group 2 calcium barium strontium hydroxides so these are the strong basis for weak acids you have organic acids for example at the knowing acids and then there are others as well like meth annoying is it proper knowing as it etc etc please take note H F is also a weak acid HF is not as strong as it do not confuse hitch F with HCl HBR H I this tree HCl HBR hir strong acids but HF is a weak and finally weak bases and you have only one example to remember and that is ammonia and let's take a look at some examples classify each of the following these of substances as a strong weak or non electrolyte they ought to get a 5 compounds here calcium chloride nitric acid at the norm for me as it sometimes we see met annoying acid or and potassium hydroxide so let's look at the answer calcium chloride so calcium chloride you know is an ionic compound being an ionic compound it is therefore a strong electrolyte nitric acid is a strong acid therefore it is also a strong electrolyte ethanol is a molecular compound being a molecular compound it is a non electrolyte forming a C or sometimes called Metanoia C is a weak acid and therefore is a weak electrolyte and finally potassium hydroxide being a strong base is a strong electrolyte
