Calculate the pH of resulting mixtures.
`10" ml of " 0.2 M Ca (OH)_(2) + 25 " ml of " 0.1 ` M HCl

Explanation

To calculate the pH of the resulting mixture of 10 ml of 0.2 M Ca(OH)₂ and 25 ml of 0.1 M HCl, follow these steps:

### Step 1: Calculate the moles of Ca(OH)₂ and HCl

1. **Moles of Ca(OH)₂**:
\[ \text{Moles of Ca(OH)₂} = \text{Molarity} \times \text{Volume (L)} = 0.2 \, \text{M} \times 0.010 \, \text{L} = 0.002 \, \text{moles} \]
