Question

Copper is purified by electrolytic refining of blister copper. The correct statement(s) about this process is (are) : (A) Impure Cu strip is used as cathode (B) Acidified aqueous CuSO4 is used as electrolyte (C) Pure Cu deposits at cathode (D) Impurities settle as anode mud

Tardigrade Admin · Accepted Answer

(i) Due to acidified aqueous CuSO4, conduction is increased (ii) Cathode is made by pure Cu (iii) Anode is made by Impure Cu (iv) Ag and Au are settle down as a anode mud
