Question

A 5 molar solution of $H_{2}S{O}_4$ is diluted form $1L$ to $10L$. What is the normality of the solution?

• A. $0.25N$
• B. $1N$
• C. $2N$
• D. $7N$

Answer 1

The correct option is B $1N$

$N_1{V}_1=N_2{V}_2$
Given, molarity of $H_{2}S{O}_4=5M$,
$N_1=$ Molarity $\times$ basicity $=5\times 2=10$
$V_1=1L,V_2=10L,N_2=$?
$N_1{V}_1=N_2{V}_2$
$10\times 1=N_2\times 10$
$\therefore N_2=1N$
