Question

The pH of the solution obtained on neutralisation of $40mL$ of $0.1M$ $NaOH$ with $40mL$ of $0.1M$ ${CH}_{3}COOH$ is:

• A. $7$
• B. $8$
• C. $6$
• D. $3$

Answer 1

Answer: (B)

$8$

As $NaOH$ is a strong base and ${CH}_{3}COOH$ is a weak acid, on neutralisation of $40mL$ of $0.1M$ $NaOH$ with $40mL$ of $0.1M$ ${CH}_{3}COOH$, we obtain a basic solution of $pH>7$. Hence, option (b) is correct.
