Ammonium acetate is going to be a chemical compound that has a longer chemical formula of NH4CH3CO2 and it is going to appear as a white solid. Typically, you can obtain ammonium acetate from the reaction of both ammonia and acetic acid and it can be purchase commercially. Since this is the salt of a weak base and a weak acid, you’re going to find that this is most commonly used as a buffer solution because it is volatile at low pressures.
