Question

The normality of 30 volume H2O2 solution is :

• A. 3.57
• B. 7.53
• C. 5.36
• D. 5.73

Answer 1

Answer: (C)

5.36

Answer 2

30 vol = 3.035 × 3 = 9.105% H2O2

100 ml sol contain 9.105 gms H2O2

Hence 1000 ml solution contain 91.05 gms H2O2

Strength of H2O2 = 91.05 gms /lit, basicity of H2O2 = 2

Equivalent wt of H2O2 = $\left( \frac{34}{2} \right)$ = 17

Normality =$\frac{Strength}{Eq.wt.} = \frac{91.05}{17}$= 5.3558
