Two methods of salt preparation
WebFor this reason, many methods of making salts involve the reaction of a suitable compound (or the metal itself, if it is sufficiently reactive) with an acid. Insoluble salts can be made by precipitation reactions. In this method, solutions of two soluble compounds are mixed, and an insoluble salt forms along with a soluble product. WebAmmonium sulfate, (NH 4) 2 SO 4, is a salt. used as a fertiliser. It can be manufactured by reacting ammonia solution with sulfuric acid: ammonia + sulfuric acid → ammonium sulfate
