Calculate pH values of (i) 0.2 M `H_(2)SO_(4)` solution (ii) 0.2M `Ca(OH)_(2)` solution.

Explanation

To calculate the pH values of the given solutions, we will follow these steps:

### (i) Calculation of pH for 0.2 M `H₂SO₄` solution:

1. **Identify the dissociation of `H₂SO₄`:**
- Sulfuric acid (`H₂SO₄`) is a strong acid and dissociates completely in water:
\[
H_2SO_4 \rightarrow 2H^+ + SO_4^{2-}
