When it comes to oxy acids, Oxy acids represent our second type of acid. Now we're going to say they represent covalent compounds because they're acids. They contain hydrogen ion as well, but now they're bonded to a polyatomic ion containing oxygen, and it's pretty clear why that is because the name is Oxy, highlighting the fact that we have oxygen present now.

So how could we form an Oxy acid? Well, here we have our H ion, so H1, and let's just think of a polyatomic ion that possesses oxygen. Here we could have NO3-. NO3- is our nitrate ion. And remember, when the numbers in the charges are the same, they just simply cancel out and you combine together your elements. So HNO3 would represent an Oxy acid.

It is covalent because it possesses only nonmetals, it has your hydrogen ion at the beginning of the compound structure. And altogether we have our oxy acid. Now that we know how they're formed and what they represent. Click on to the next video and let's go over the rules for naming them.
