Calculate the pH value of a solution obtained by mixing 50 mL of 0.2 N HCl solution with 50 mL of 0.1 N NaOH solution.

Explanation

To calculate the pH of the solution obtained by mixing 50 mL of 0.2 N HCl with 50 mL of 0.1 N NaOH, we can follow these steps:

### Step 1: Calculate the moles of HCl and NaOH
1. **Calculate moles of HCl:**
- Normality (N) = 0.2 N
- Volume (V) = 50 mL = 0.050 L
- Moles of HCl = Normality × Volume = 0.2 N × 0.050 L = 0.010 moles
