Given below are two statements.
Statement I: During electrolytic refining, blister copper deposits precious metals.
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.

We need to evaluate both statements about electrolytic refining of copper.

Evaluating Statement I:

During electrolytic refining, impure blister copper is used as the anode. When the anode dissolves, less reactive precious metals like gold (Au) and silver (Ag) do not dissolve and settle at the bottom as anode mud. Thus, blister copper effectively deposits (releases) precious metals during the refining process.

Statement I is true.

Evaluating Statement II:

In the electrolytic purification of copper, blister copper (impure copper, ~98-99% pure) is indeed used as the anode. A thin strip of pure copper is used as the cathode, and an acidified copper sulphate solution serves as the electrolyte. At the anode, copper dissolves as $$Cu^{2+}$$, and at the cathode, pure copper is deposited.

Statement II is true.

Both Statement I and Statement II are true.

The correct answer is Option A.
