Ammonium acetate is a salt of a weak acid (acetic acid) and a weak base (ammonia). When dissolved in water, it undergoes hydrolysis to produce a slightly acidic solution. However, the conjugate acid and base in this case are both weak, resulting in a relatively neutral solution overall. Therefore, the aqueous solution made from solid ammonium acetate would be neutral.
