Question

During electrolysis of copper sulphate solution, the positive ___ ions accept electrons and get deposited at the ___ electrode.

• A. copper, negative
• B. sulphate, positive
• C. copper, positive
• D. sulphate, negative

Answer 1

The correct option is A copper, negative

During electrolysis of copper sulphate solution, the positive copper ions are attracted by the negative terminal where they accept electrons and get deposited on the negative terminal.

Hence, the mass of the negative electrode increases while that of the positive electrode decreases.
