Statement: Most compounds that produce this in aqueous solution are ionic. Does this statement refer to an acid or a base or both?

I am wondering what "this" means. I would guess salts is the answer, but honestly, it is not clear.

Exactly what my mom asked,what is this. But that is the statement given on my homework. The only answer I can give is does it refer to an acid, a base or both.

acids and bases are not ionic. Salts are.

This statement refers to bases. In aqueous solution, bases typically produce hydroxide ions (OH-) and are generally classified as ionic compounds. Acids, on the other hand, produce hydrogen ions (H+) in aqueous solution and may or may not be ionic compounds. However, in this specific statement, it is referring to bases as the compounds that produce the mentioned effect in aqueous solution.
