If, for example, we add ammonia to a solution of magnesic sulphate, magnesia is precipitated, and ammonic sulphate remains in solution. This precipitation of magnesia is the action of cohesion. But if dry ammonic sulphate and dry magnesia are heated together, ammonia is expelled and magnesic sulphate is formed.Get price
