Find the volume strength of 1.6 N H₂O₂ solution

Open in App

Solution

Equivalent weight of H₂O₂ = 17
Consider the reaction:
2H₂O₂ $\to$ 2H₂O + O₂
Now 22.4L of O₂ is obtained by 68g of H₂O₂ (2 moles of H₂O₂ = 68g) at N.T.P
Normality = $\frac{m a s s o f s o l u t e}{e q u i v a l e n t m a s s o f s o l u t e \times v o l u m e i n l i t e r s}$
$1.6 = \frac{m a s s o f H_{2} O_{2}}{17 \times 1} m a s s o f H_{2} O_{2} = 27.2 g$
1.6N of H₂O₂ contains 27.2g of H₂O₂
So O₂ produced by 27.2g of H₂O₂= $\frac{22.4}{68} \times 27.2 = 9.05 L$
Hence volume strength of 1.6N H₂O₂ is 9.05
