The reaction of carboxylic acids are classified as follows:
Acidity
Reactions with metals and alkalies
The carboxylic acids like alcohols evolve hydrogen with electropositive
metals and form salts with alkalies similar to phenols However, unlike
phenols they react with weaker bases such as carbonates and
hydrogencarbonates to evolve carbon dioxide This reaction is used to
detect the presence of carboxyl group in an organic compound Carboxylic acids dissociate in water to give resonance stabilised
carboxylate anions and hydronium ion
