Carboxylic acids can donate a proton (H⁺) from the hydroxyl group (-OH) in the carboxyl group (-COOH). This proton dissociation is the key characteristic of an acid. The general reaction is:
C arboxylic acids reacted with weak bases, such as carbonates and bicarbonates, carbon dioxide was formed REACTION WITH BASE Carboxylic acids on reaction with bases give salt and water Reaction with weak bases
