What is seen to happen to the colour of the copper sulphate solution if platinum electrodes are used ? Explain this observation .

Explanation

**Step-by-Step Solution:**

1. **Identify the Initial State of the Solution**: The copper sulfate solution is initially blue in color due to the presence of copper(II) ions (Cu²⁺) in the solution.

2. **Electrolysis Process**: When electrolysis is performed on the copper sulfate solution using platinum electrodes, an electric current is passed through the solution.

3. **Movement of Ions**: During electrolysis, the copper ions (Cu²⁺) move towards the cathode (negative electrode) where they gain electrons and are reduced to form copper metal. The sulfate ions (SO₄²⁻) move towards the anode (positive electrode) where they are oxidized.
