Why is `H_2S` more acidic than `H_2O` ?

Explanation

To understand why \( H_2S \) is more acidic than \( H_2O \), we need to analyze the properties of both molecules, focusing on bond strengths and the ability to release \( H^+ \) ions in aqueous solution.

### Step-by-Step Solution:

1. **Definition of Acidity**:
- Acidity is defined by the ability of a substance to donate protons (\( H^+ \)) in an aqueous solution. The more readily a substance can release \( H^+ \), the stronger the acid.

2. **Comparison of Bond Strengths**:
...
