Have you changed compounds. Your earlier question concerned 4-aminoethyl benzoate. Straight benzoic acid would form a salt since it is an acid reacting with a base, NaOH.
ArCOOH + NaOH ==> H2O + ArCOONa where Ar is the benzene ring.
c). If HCl is added to the tube, HCl neutralizes the NaOH and reprecipirates the benzoic acid.
