Question

Calculate the strength of 10 volume solution of hydrogen peroxide.

• A. $30.35\ \text{g L}^{-1}$
• B. $60.71\ \text{g L}^{-1}$
• C. $45.51\ \text{g L}^{-1}$
• D. $15.175\ \text{g L}^{-1}$

Hint:

To convert volume strength of $H_2O_2$ into g L$^{-1}$, multiply the volume strength by 3.035.

Answer 1

The Correct Option is A

Step 1: Understand volume strength of $H_2O_2$.
Volume strength of hydrogen peroxide is defined as the volume (in litres) of oxygen liberated at NTP by one litre of the solution.
Step 2: Relation between volume strength and strength in g L$^{-1$. For hydrogen peroxide,
\[ \text{Strength (g L}^{-1}) = \text{Volume strength} \times 3.035 \]
Step 3: Substitute the given value.
\[ \text{Strength} = 10 \times 3.035 \]
\[ \text{Strength} = 30.35\ \text{g L}^{-1} \]
Step 4: Conclusion.
The strength of 10 volume hydrogen peroxide solution is $30.35\ \text{g L}^{-1}$.
