Calculate the pH of `N/(1000)` sodium hydroxide (NaOH) solution assuming complete ionisation.

Explanation

To calculate the pH of a \( \frac{N}{1000} \) sodium hydroxide (NaOH) solution, we will follow these steps:

### Step 1: Understand the relationship between Normality and Molarity
Sodium hydroxide (NaOH) is a strong base that completely ionizes in solution. The normality (N) of a solution is related to its molarity (M) by the equation:
\[ \text{Normality} = \text{Molarity} \times n \]
where \( n \) is the number of replaceable hydroxide ions (OH\(^-\)) per formula unit of the solute. For NaOH, \( n = 1 \).
