Q.
A $5$ molar solution of $H_2SO_4$ is diluted from 1 litre to a volume of 10 litres, the normality of the solution will be
AIPMTAIPMT 1991Some Basic Concepts of Chemistry
Solution:
$N _{1} V _{1}= N _{2} V _{2}$
Given, molarity of $H _{2} SO _{4}=5 M$,
$N _{1}=$ Molarity $\times$ basicity $=5 \times 2=10$
$V _{1}=1\, L,\, V _{2}=10\, L,\, N _{2}=?$
$N _{1} V _{1}= N _{2} V _{2}$
$10 \times 1= N _{2} \times 10$
$\therefore N _{2}=1\, N$
