Using a chemical equation, explain why ethyl 4-aminobenzoate is insoluble in water at room temperature but soluble in dilute HCl. The structure of sodium benzoate is given. Upon addition of water, the salt readily dissolves. However, when HCl is added to this solution, a white precipitate forms. Using an equation, provide the identity of the white precipitate and explain its formation. The structure of the chloride salt of ethyl 4-aminobenzoate is shown below. Upon addition to water, the salt readily dissolves. However, when NaOH is added to this solution, a white precipitate forms. Using an equation, provide the identity of the white precipitate and explain its formation.
