When an aqeous solution of copper (II) sulphate is electrolysed between two copper electrodes , the blue colour ions are discharged and deposited as metallic copper at cathode . But the blue colour of the solution does not fade . Explain.

Explanation

### Step-by-Step Solution:

1. **Understanding Electrolysis of Copper(II) Sulphate**:
- When an aqueous solution of copper(II) sulphate (CuSO₄) is electrolyzed using copper electrodes, the solution contains copper ions (Cu²⁺) and sulfate ions (SO₄²⁻).

2. **Electrolysis Process**:
- At the **cathode** (negative electrode), copper ions (Cu²⁺) gain electrons and are reduced to form metallic copper (Cu):
