Question

Given below are two statements.

$\text{Statement-I:}$ During electrolytic refining, blister copper deposits precious metals.

$\text{Statement-II:}$ In the process of obtaining pure copper by electrolysis method, copper blister is used to make the anode.

In the light of the above statements, choose the correct answer from the options given below.

• A. $\text{Statement-I}$ is true but $\text{Statement-II}$ is false.
• B. Both $\text{Statement-I}$ and $\text{Statement-II}$ are false
• C. $\text{Statement-I}$ is false but $\text{Statement-II}$ is true
• D. Both $\text{Statement-I}$ and $\text{Statement-II}$ are true.

Answer 1

The correct option is D Both $\text{Statement-I}$ and $\text{Statement-II}$ are true.

Copper is refined using an electrolytic method. Anodes are of impure copper and pure copper strips are taken as cathode.

Impurities from the blister copper deposit as anode mud which contains antimony, selenium, tellurium,
silver, gold and platinum.

Hence, both statements are true.
