When it comes to naming oxyacids, it's first important to remember your polyatomic ions. Now if you don't remember your polyatomic ions or you haven't watched my videos on them, I suggest you pause this video and go back and take a look at those videos first. Then come back and we can tackle naming oxyacids together. Alright. So for those of you who are ready, let's go. We're going to say here rules for naming oxyacids. Rule 1, if the polyatomic ion ends with -ate, then change the ending when it's in its acid form to -ic acid. Here, we have a memory tool that will help us. So here we're gonna say I ate in acid, and it was icky. Now, don't go biting into acids or eating them in any way, but just remember that -ate goes with icky. Okay? So in its polyatomic ion form, it's -ate, but in its acid form, we change the ending to -ic acid. So here we have H⁺ with NO₃^-. Remember, NO₃^- is your nitrate ion. When I combine them together to give me HNO₃, that is our oxyacid form. Here, the -ate ending changes to -ic, acid. So nitrate becomes nitric acid. But remember, we also have polyatomic ions that end with -ite. What do we do in those situations? Well, we're gonna say if the polyatomic ion ends with -ite, then in its acid form, we'll change the ending to -ous acid. And again, we have a great memory tool, so I only bite into things that are delicious. So this will help us remember, if we have a polyatomic ion that ends with -ite, in its acid form it becomes -ous ending, -ous acid. So here we have H⁺ with NO₂^-. NO₂^- is our nitrite ion. When it combines with H⁺, we get HNO₂, which is our oxyacid form. The -ite ending changes to -ous acid. So nitrite becomes nitrous acid. So again, unless you know your polyatomic ions, it gets pretty tricky in terms of naming the oxyacid. Now that we've seen the rules for this, let's continue on with some questions and test what we've learned.
