Sodium Hydroxide and Acetic Acid

NaOH + CH3COOH → CH3COONa + H2O

概述

Sodium hydroxide reacts with acetic acid to form sodium acetate and water. Since acetic acid is a weak acid, this neutralization produces a basic solution (pH about 8.9) due to acetate ion hydrolysis. The heat of neutralization is slightly less than for strong acid-strong base pairs.
