Question

Volume (in litres) of 0.1M $H_2{SO}_4$ required to completely neutralize 1 litres of 0.5M NaOH is:

• A. $5$
• B. $2.5$
• C. $0.5$
• D. $10$

Answer 1

Answer: (B)

$2.5$

Number of equivalent should be same,

$N_1{V}_1=N_2{V}_2$

$H_{2}S{O}_4\Rightarrow 2$ acidic-Hydrogen

$0.1\times 2\times V_1=0.5\times 1\times 1$

$V_1=\frac{0.5}{0.2}$

$V_1=2.5$ litre
