Question

Volume of 0.1M $H_2{SO}_4$ is required to neutralise 50ml of 0.2M NaOH solution is:

• A. $25$
• B. $100$
• C. $75$
• D. $50$

Answer 1

Answer: (D)

$50$

No. of equivalents of acid and base should be same.
$N_1{V}_1=N_2{V}_2$
$(0.1\times 2)V_1=(0.2\times 1)50$
$V_1=\frac{2\times 50}{2}$
$V_1=50ml$
