Question

The process of purification of an impure metal is like:
A. electroplating a metal on the same type of metal
B. electroplating a metal on another type of metal
C. producing a chemical compound by electrolysis
D. decomposing a chemical compound by electrolysis.

Answer 1

Answer:

A)

Explanation:

A)is correct answer because if you add other metal for electroplating it form an another impure metal for

Answer 2

The process of purification of an impure metal is like A. electroplating a metal on the same type of metal.

Explanation:

• Impure and pure metal are taken as electrode and water soluble salt of the metal is taken as electrolyte.
• Here, impure copper metal is taken as cathode and pure copper metal is taken as anode. Copper sulfate solution is taken as electrolyte.
• When electricity is passed through electrode, the atoms of the impure metal reacts with electrolyte and the metal in electrolyte is deposited into cathode.
• After sometimes, the impure metal electrode becomes thinner and pure metal electrode becomes thicker.
