As the name implies, they are acids and react with bases to form carboxylate salts, in which the hydrogen of the -OH group is replaced with a metal ion. Thus, acetic acid (vinegar) reacts with sodium bicarbonate (baking soda) to form sodium acetate, carbon dioxide, and water: CH3COOH + NaHCO3? -> CH3COONa + CO2 + H2O |
