Question

The strength in volumes of a solution containing 30.36 $gmlitr{e}^{-1}$ of $H_2{O}_2$ is

• A. 10 volume
• B. 20 volume
• C. 5 volume
• D. None of these

Answer 1

The correct option is A

10 volume

E.W. of $H_2{O}_2$ = 17

N= $\frac{30.36}{17}$ =1.78N

Volume strength =5.6 $\times$ Normality

5.6 $\times$ 1.78=10 litre(approx.)
