Does a reaction happen if you mix an organic acid salt and an aqueous base?
In a case like this, there would be no further reaction. It is possible that if you had a highly soluble organic salt like lead acetate or lead gluconate and added sodium benzoate, you would get a precipitate of lead benzoate. Or if you added sodium hydroxide, you would get lead hydroxide and the sodium and benzoate ions would remain n solution.
