Webdeprotonated. 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. WebHowever ethyl 4-aminobenzoate won't be soluble in 1.0 M NaOH because it has no acidic functional groups as HCL has. Ethyl 4-aminobenzoate was analyzed to be soluble in 1.0 M HCl, but upon adding 6.0 M of sodium hydroxide to the solution of ethyl 4-aminobenzoate and 1.0 M of HCL, ethyl 4-aminobenzoate became insoluble.
