Every semester I get asked. We're about to find out. All right, let's do this. Hello hello Melissa Maribel here and I help students like you understand what you just learned in class so you stress less and you graduate faster. Hit that subscribe button if you want to pass Chemistry. On to naming acids. Remember all acids begin with H in front or a hydrogen in front. That is your clue that it is an acid. There are two specific types of acids. Ones with oxygen and ones without oxygen. The ones without oxygen begin with a prefix of "Hydro." That hydro is your clue that there is no oxygen. Your setup begins with your hydro as your prefix, next we'll have our root name of our element ending in "ic" acid. The acid tells us that there is a hydrogen in front. Remember hydro just tells you there is no oxygen. For example, hydroiodic acid, Hydro tells us no oxygen. The acid portion tells us there's a hydrogen in front and that "iod" tells us the root name of our element or iodine. Balance out your charges and we'll get the friendliest of all the acids, H I, or hydroiodic acid. Let's go in reverse, now if you're given your chemical formula and asked for the acids name. We have HF, there is no oxygen so that tells us, hydro, our prefix is hydro. We'll take this sort of set up, just placing our root name of our element fluorine and you get hydrofluoric acid. Remember that acid tells us the hydrogen in front. There is no oxygen that's why it's hydro and fluoric just tells us that it's fluorine, Hydrofluoric acid. The second type of does contain oxygen, so our prefix is gone, there is no prefix for this second type of acid. Your setup which once again has no prefix, it goes right into the root word or root name of your element ending in "ous" acid. For example, if we were to have nitrous acid that "ous" actually refers to "ite" and our polyatomic atoms come back into play. We have nitrite, so whenever we're given us it means "ite." The acid refers to a hydrogen being in front. We'll have nitrite which was NO2- charge and our acid placing that hydrogen in front. Balance out your charges and we get HNO2. The next set up jumping right into that root name of your element ending in "ic" acid. For example, nitric acid, the "ic" goes with another polyatomic which is "ate." So "ic" goes with "ate" nitric tells us really there's a nitrate and the acid once again just states that there is a hydrogen in front. We'll balance out our charges and we get HNO3. Let's go backwards once again. We're given our chemical formula and asked to figure out the name of the acid. You're given H3PO3. There is an oxygen which tells us there is no prefix. The H says it's an acid. This is phosphite remembering your polyatomic atoms. PO3 is phosphite. "ite" goes with "ous." We will have this sort of set up and it actually is phosphorous acid. Be aware of this case, we added an "r" that is just something that you have to know unfortunately. In chemistry this is how they named phosphorous acid. Now if we're given H3PO4, there is another oxygen so no prefix once again. The H tells us it's an acid, this is phosphate. The "ate" goes with "ic." Your setup looks just like this and in this case we do add another "r" once again, so it's phosphoric acid. This is another type that we have to know. So for any sort of PO4 or PO3, any of those phosphates or phosphites, they add an "r." To help you remember naming acids with oxygen, where the "ate" goes with "ic" and the "ite" goes with "ous," remember the saying. I ATE organIC apples despITE being poisonOUS (Witch laugh) (music) I hope that went well, if you need some more help check the description box I've linked some practice problems and reserve your spot today for live tutoring with me.
