Benzoic Acid and Sodium Hydroxide
C6H5COOH + NaOH → C6H5COONa + H2O
نظرة عامة
Benzoic acid, the simplest aromatic carboxylic acid, reacts with sodium hydroxide to form water-soluble sodium benzoate. Benzoic acid itself is poorly soluble in water but dissolves readily in base. This solubility difference is exploited in liquid-liquid extraction to separate acids from neutral compounds.
