How may it be detected ? By what pro-cess is aqua ammoniae made? What is the nature of ammonium? Inwhat State may it be obtained ? AMMONIUM. 251 amalgam of potassium and mercury in water of these circumstances, the mercury swells, and event-ually becomes of a soft consistency like butter, preservingits metallic aspect completely.
