A zinc plate was kept in a glass container having copper sulphate solution. On examining it was found that the blue colour of the solution is getting fader and fader. After a few days when the zinc plate was taken out of the solution, a number of small holes were noticed in it. State the reason and give chemical equation of the reaction involved.

Explanation

### Step-by-Step Solution

1. **Observation of the Experiment**: When a zinc plate is placed in a copper sulfate solution, the blue color of the solution begins to fade over time. This indicates a chemical reaction is taking place.

2. **Understanding the Reactivity of Metals**: To understand why this reaction occurs, we refer to the metal activity series. In this series, zinc is more reactive than copper. This means that zinc has a greater tendency to displace copper from its compounds.

3. **Displacement Reaction**: Since zinc is more reactive than copper, it can displace copper from copper sulfate (CuSO₄). The reaction can be represented as follows:
\[
