Question

in the process of purification of copper metal a thin plate of pure Copper and nothing rod of impure copper are used as electrodes in this process solution is used as an electrolyte
a. name the electrode which is used as cathode
b. name the electrode which is made the anode
c. name the salt solution used as an electrolyte in this process
d. mention two practical applications of electroplating

Answer 1

Do you remember how a metal 

anodecan get involved in 

electrolysis when we electroplate an object?

The same idea is used in industry to purify impure copper metal. The impure copper is made the 

anode (+) and a thin piece of pure copper is made the 

cathode (−). An 

electrolyte containing copper ions is used. 

Look at the process in Fig.1 below:

Answer 2

Hey dear here is your answer!!!!!

___________________________

a. The pure metal strip is used as cathode.

b.  Impure metal is used as anode.

c. Copper Sulphate (CuSO₄) is used as electrolyte.

d. 1. Electroplating is used by car manufacturers to electro plate their car parts.

2. Electroplating is used in the making of utensils.
