An oxyacid, oxoacid, or ternary acid is an acid that contains oxygen. Specifically, it is a compound that contains hydrogen, oxygen, and at least one other element, with at least one hydrogen atom bonded to oxygen that can dissociate to produce the H⁺ cation and the anion of the acid. For example, nitric acid, HNO3, in which the nitrogen (N) atom has an oxidation number of +5, is a stronger acid than nitrous acid, HNO2, where the nitrogen oxidation state is +3. "How do you notice a oxyacid?" Answer: To name oxyacids, you must first be able to recognize them by the general formula HaXbOc, with X representing an element other than hydrogen or oxygen. It will also be useful for you to know the names of the polyatomic oxyanions, because many oxyacid names are derived from them. "What is the strongest base?"
