How do you name acid compound?

Answer 1

By one of two methods:

1-common name (CH3COOH common name acetic acid)

2-IUPAC name according to number of carbons (CH3COOH common name acetic acid but in IUPAC called methanoic acid)

Answer 2

To name an acid compound, use the prefix "hydro-" followed by the root of the nonmetal with the suffix "-ic" for binary acids or "-ous" for acids containing oxygen. For example, HCl is hydrochloric acid, and H2SO3 is sulfurous acid.
