What would a general formula of an acid always start with? What does the general formula of an acid have to end with? Where would you put a subscript in a general formula and why is it put there?

Answer 1

A general formula of an acid always start with an hydronium ion or H+. The general formula of an acid have to end with an anion. As acids, these compounds are named starting with the prefix "hydro-," then adding the first syllable of the anion, then the suffix "-ic."
