Which of the following metals can deposit copper from copper sulphate solution? (1) platinum (2) Mercury (3) Iron (4) Gold
by

1 Answer

Answer :

(3) Iron Explanation: The iron displaces copper from its salt, to make iron sulfate solution and deposit a thin coating of metallic copper on the surface of the metal. In general, any metal higher than copper in the "electromotive series" will displace copper from copper sulfate solution.
