Question

200 ml of 0.25 M $H_2{SO}_4$ is diluted to 250 ml. Normality of the solution becomes:

• A. $0.2N$
• B. $0.25N$
• C. $0.4N$
• D. $0.5N$

Answer 1

The correct option is C $0.4N$

We have, $N_1{V}_1=N_2{V}_2$ and $N=n\times M$

for $H_{2}S{O}_4$ we have n-factor=2

So, we have,

$200\times 0.25\times 2=N\times 250$

$N=0.4N$
