In the electrolysis of CuCl2 solution using Cu electrodes, the weight of Cu anode increased by 2 gram at cathode. In the anode,
Correct answer: D. 2 gram of copper goes into solution as Cu2+
- A. 0.2 mole of 2 Cu+ will go into solution
- B. 560 ml O2 liberate
- C. No loss in weight
- D. 2 gram of copper goes into solution as Cu2+
Explanation
During electrolysis of CuSO4 solution using Cu electrodes, the cell reaction is: Anode: Cu (s) → Cu++ + 2e- Cathode: Cu++(aq) + 2e- → Cu(s)The loss in weight of anode is equal to gain in weight of cathode.

About Electrochemistry
Electrochemistry describes electron transfer through oxidation and reduction, identifies oxidizing and reducing agents, and applies oxidation numbers to balance redox equations. It also covers electrode potential and the standard hydrogen electrode, which provides the reference for comparing the reduction tendencies of other electrodes.
