Ascorbic Acid and Sodium Hydroxide

C6H8O6 + NaOH → NaC6H7O6 + H2O

개요

Ascorbic acid (vitamin C) reacts with sodium hydroxide to form sodium ascorbate and water. Despite its name, ascorbic acid is a moderately weak acid (pKa = 4.17) due to the enediol structure that stabilizes the conjugate base through resonance. Sodium ascorbate is better tolerated by the stomach than ascorbic acid.
