MCQ

For electroplating an iron object with copper metal or copper plating, we should not follow the method is or are:

A
The iron object is made negative electrode.
B
The copper plate is made positive electrode.
✓
Iron sulphate solution is taken as electrolyte.
D
Copper sulphate solution is taken as electrolyte.

✓

Answer

Correct option: C.

Iron sulphate solution is taken as electrolyte.

We should not follow the method is option $[c].$ For electroplating an iron object with copper metal or copper plating, we should follow the method is: the iron object is made negative electrode. The copper plate is made positive electrode. Copper sulphate solution is taken as electrolyte. Because the metal object on which electroplating is to be done is made the negative electrode or cathode. The metal whose layer is to be deposited is made the positive electrode and a water$-$soluble salt of the “metal to be deposited” is taken as the electrolyte $($the electrolyte contains the metal to be deposited in the form of soluble salt$).$
