State one relevant observation for each of the following reactions :
Water is added to anhydrous copper sulphate

Explanation

**Step-by-Step Solution:**

1. **Identify the Reactants**: The reaction involves anhydrous copper sulfate (CuSO4) and water (H2O). Anhydrous copper sulfate is a white crystalline solid.

2. **Add Water to Anhydrous Copper Sulfate**: When water is added to anhydrous copper sulfate, it begins to interact with the solid.

3. **Formation of Coordinate Bonds**: Water molecules form coordinate bonds with the Cu²⁺ ions present in the anhydrous copper sulfate. This process involves the water molecules coordinating with the copper ions.
