Acetic Acid and Sodium Hydroxide Neutralization

CH3COOH + NaOH → CH3COONa + H2O

Descripción general

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.

Ejemplo cotidiano

Sodium acetate is used in hand warmers and hot ice demonstrations, where a supersaturated solution crystallizes exothermically.

Importancia industrial

El acetato de sodio se utiliza como conservante alimentario (E262), en la industria textil y como fuente de carbono en el tratamiento de aguas residuales para la eliminación biológica de nutrientes.
