Yes, since it fulfils the Bronstead-Lowry acid theory.

#### Explanation:

Bronstead-Lowry theory states that an acid is a proton (${\text{H}}^{+}$ ion) donor and a base is a proton acceptor.

If we look at the reaction of acetic acid with sodium hydroxide, it becomes clear that it is an acid.

$\text{CH"_3"COOH" + "NaOH" rarr "CH"_3"COONa" + "H"_2"O}$

As you can see, acetic acid has donated a proton to sodium hydroxide which accepted it. Thus, we can conclude that acetic acid is an acid and that sodium hydroxide is a base.
