In electrolytic refining of blister copper
Options
- Aacidified [ Cu ( NH ₃ )₄ ]²⁺ can be used as electrolyte.
- Bpure Cu deposits at anode and metal impurities Ag and Au go into the * solution as ions.
- Cpure Cu deposits at cathode while Ag and Au remain at anode.
- DCu ²⁺ reduces to Cu at anode and Cu oxidizes to Cu ²⁺ at cathode.
Correct answer
C. pure Cu deposits at cathode while Ag and Au remain at anode.
