Question

A solution contains $10$ ml of $0.1$ $N$ $NaOH$ and $10$ ml of $0.05N{a}_{2}S{O}_4$. $pH$ of this solution is:

• A. 7
• B. less than 7
• C. greater than 7
• D. zero

Answer 1

The correct option is C greater than 7

The $pH$ of the solution will be greater than 7 due to the presence of $NaOH$.

The $N{a}_{2}S{O}_4$ is a salt of strong acid and strong base and thus the $pH$ is not much affected by it.
