Give the chemical tests distinguish between the following pairs:
Copper sulphate and Iron (II) sulphate.

Explanation

To distinguish between copper sulfate (CuSO4) and iron (II) sulfate (FeSO4), we can perform a chemical test using ammonium hydroxide (NH4OH). Here are the steps involved in the process:

### Step-by-Step Solution:

1. **Prepare the Solutions**:
- Take a small amount of copper sulfate solution (CuSO4) in a test tube.
- In another test tube, take a small amount of iron (II) sulfate solution (FeSO4).
