For instance, hydrochloric acid (HCl) ionizes in water, producing chloride and hydronium ions. Ammonia (NH3) acts as a base by accepting a proton from HCl, forming ammonium and water. It also highlights the role of biological acids, particularly those with carboxyl groups like acetic acid, and notes that biological bases often contain amino groups, with bicarbonate ions being significant bases.
