    Answer: Two compounds below that can be used to make a buffer solution are acetic acid and acetate ion.

    Explanation:

    A solution that helps in resisting change in pH when a small amount of acid or base is added to it is called a buffer solution.

    A buffer solution consists of a mixture of weak acid and its conjugate base.

    Acetic acid has a chemical formula CH_{3}COOH and its conjugate base is CH_{3}COO^{-}.

    This base is also called acetate ion.

    Acetic acid is a weak acid because it dissociates weakly when added to a solvent like water.

    Therefore, acetic acid and acetate ion will form a buffer solution.

    Thus, we can conclude that two compounds below that can be used to make a buffer solution are acetic acid and acetate ion.
