Calculate the pH of solution obtained by mixing 150 mL of 0.2 M HCl and 150 mL of 0.1 M NaOH.

Explanation

To calculate the pH of the solution obtained by mixing 150 mL of 0.2 M HCl and 150 mL of 0.1 M NaOH, follow these steps:

### Step 1: Calculate the number of moles of HCl and NaOH
- **HCl**:
\[ \text{Moles of HCl} = \text{Concentration} \times \text{Volume} = 0.2 \, \text{M} \times 0.150 \, \text{L} = 0.030 \, \text{moles} \]
