WebA fine powder of aluminium metal reacts explosively on contact with liquid oxygen; under normal conditions, however, aluminium forms a thin oxide layer (~5 nm at room temperature) [37] that protects the metal from further corrosion by oxygen, water, or dilute acid, a process termed passivation. WebTry this class practical to explore an equilibrium involving copper (II) ions. In this experiment, students add ammonia to a solution of copper (II) sulfate, observe the colour changes taking place, and then reverse the reaction by the addition of sulfuric acid. The experiment is best carried out by students working individually.
