Write chemical reactions to show the amphoteric nature of water.

Explanation

To demonstrate the amphoteric nature of water, we can show how it can act both as an acid and as a base through specific chemical reactions.

### Step-by-Step Solution:

1. **Understanding Amphoteric Nature**:
Water (H₂O) is considered amphoteric because it can act both as an acid (donating a proton) and as a base (accepting a proton).

2. **Water Acting as a Base**:
