Normal carbonates are formed when equivalent amounts of acid and base react; bicarbonates, also called acid carbonates or hydrogen carbonates, are formed when the acid is present in excess. Sodium carbonate, Na 2 CO 3, sodium bicarbonate, NaHCO 3, and potassium carbonate, K 2 CO 3, are widely used. Smelling salts is ammonium carbonate.
