Calculate the PH of the resultant mixture :
10 mL of 0.2 M ` Ca(OH)_2` + 25 mL of 0.1 M `HCl `

Explanation

To calculate the pH of the resultant mixture of 10 mL of 0.2 M \( \text{Ca(OH)}_2 \) and 25 mL of 0.1 M HCl, we can follow these steps:

### Step 1: Write the balanced chemical equation
The reaction between calcium hydroxide and hydrochloric acid is as follows:
\[ \text{Ca(OH)}_2 + 2 \text{HCl} \rightarrow \text{CaCl}_2 + 2 \text{H}_2\text{O} \]
