Q.
How many millilitres of $0.1\, N\, H_2SO_4$ solution will be required for complete reaction with a solution containing $0.125 \,g$ of pure $Na_2CO_3$?
Some Basic Concepts of Chemistry
Solution:
Meq of $H_2SO_4 = $ Meq of $Na_2CO_3$
$ 0.1 \times \frac{V}{1000} = \frac{0.125}{106} \times2$
$V = 23.6 \,mL$
