Give reasons for the following
The blue colour of aqueous copper sulphate fades when it is electrodes.

Explanation

### Step-by-Step Solution:

1. **Understanding the Blue Color of Copper Sulfate:**
- Aqueous copper sulfate (CuSO₄) appears blue due to the presence of copper(II) ions (Cu²⁺).
- The blue color is attributed to the electronic transitions of the copper ions, specifically due to the presence of unpaired electrons in the d-orbitals. The electronic configuration of Cu²⁺ is [Ar] 3d⁹, which allows for d-d transitions that absorb certain wavelengths of light, resulting in the blue color.

2. **Electrolysis Process:**
- When copper sulfate solution is subjected to electrolysis, an electric current is passed through the solution, causing chemical reactions at the electrodes.
