Acetic Acid and Sodium Hydroxide Neutralization

CH₃COOH + NaOH → CH₃COONa + H₂O

نظرة عامة

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.
