c c
Cathode & Anode
When the sample of copper with zinc impurity is to be purified by electrolysis, the appropriate electrodes are:
c c
Cathode & Anode
Show Hint
Electrolytic refining: impure anode, pure cathode.
Updated On: Mar 17, 2026
- Pure zinc Pure copper
- Impure sample Pure copper
- Impure zinc Impure sample
- Pure copper Impure sample
Hide Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
In electrolytic refining:
- Impure metal is used as anode.
- Pure metal sheet is used as cathode.
Copper gets deposited on cathode while zinc remains in solution.

Top Questions on reaction mechanism
- Given below are two statements:
Statement I: The dipole moment of R–CN is greater than R–NC and R–NC can undergo hydrolysis under acidic medium to produce R–COOH.
Statement II: R–CN hydrolyses under acidic medium to produce a compound which on treatment with SOCl$_2$, followed by the addition of NH$_3$ gives another compound (X). This compound (X) on treatment with NaOCl/NaOH gives a product, that on treatment with CHCl$_3$/KOH/$\Delta$ produces R–NC.
