www.bc.edudeprotonated. Hydrochloric acid is generally used to protonate amines. The solid forms of the acidic and basic organic compounds can be recovered from the aqueous solution using the same solubility switch principles. When acid is added to an aqueous solution that contains the salt of a deprotonated organic acid, the organic acid is re-protonated.
