Why does blue colour of copper sulphate solution start fading when a zinc rod is dipped in it?

Explanation

To understand why the blue color of copper sulfate solution starts fading when a zinc rod is dipped in it, we can break down the explanation into clear steps:

### Step 1: Identify the Components
- **Copper Sulfate Solution**: The solution is blue in color due to the presence of copper ions (Cu²⁺).
- **Zinc Rod**: Zinc is a more reactive metal compared to copper.

### Step 2: Reactivity Series
- **Reactivity Series**: Metals are arranged in a reactivity series based on their ability to displace other metals from solutions. Zinc is higher in the reactivity series than copper.
