Acetic Acid and Sodium Hydroxide Neutralization
CH3COOH + NaOH → CH3COONa + H2O
Visão geral
Acetic acid (vinegar) reacts with sodium hydroxide to form sodium acetate and water. Because acetic acid is a weak acid (Ka = 1.8 × 10⁻⁵), the resulting solution is slightly basic at the equivalence point due to acetate ion hydrolysis. The heat of neutralization is slightly less than for strong acid-strong base pairs.

Exemplo do cotidiano
Sodium acetate is used in hand warmers and hot ice demonstrations, where a supersaturated solution crystallizes exothermically.
Importância industrial
O acetato de sódio é utilizado como conservante alimentar (E262), na indústria têxtil e como fonte de carbono no tratamento de águas residuais para remoção biológica de nutrientes.
