Question

State the reaction occurring at the anode during the electrolysis of copper sulphate solution using a copper anode

Answer 1

____________________

✔ The anode (positive electrode ) is made from impure copper and the cathode (negative electrode) is made from pure copper. During electrolysis, the anode loses mass as copper dissolves, and the cathode gains mass as copper is deposited. A half-equation shows what happens at one of the electrodes during electrolysis.

Answer 2

Answer:

The electrolyte becomes blue in colour

because the copper anode being reactive releases copper ions so the anode becomes thin and no gas is relaesed.
