Hydrochloric Acid and Sodium Acetate

HCl + CH₃COONa → CH₃COOH + NaCl

Visão geral

A strong acid reacts with the salt of a weak acid to liberate the weak acid. Hydrochloric acid protonates acetate ions to form acetic acid because HCl is a much stronger acid. This reaction demonstrates the principle that stronger acids displace weaker acids from their salts.

Exemplo do cotidiano

Adding vinegar (acetic acid) to a solution of baking soda generates the characteristic fizzing because the same displacement principle applies to carbonate salts.

Importância industrial

Este princípio é utilizado na química industrial para produzir ácidos fracos a partir dos seus sais. É também a base da regulação do pH em processos de fermentação, onde os tampões de acetato são amplamente utilizados.
