Hydrogen peroxide `(H_2 O_2)` was first prepared by Thenard by acidifying barium peroxide and removal of excess water by evaporation under reduced pressure. Its strength can be expressed as weigth percentage or as volume percentage . 25% solution by weight means 25 g of hydrogen peroxide are present in 100 g of solution and 25 volume of hydrogen peroxide means that 1 litre of this solution will give 25 L of oxygen at NTP.
Calculate the volume strength of a 2N `H_2 O_2` solution.

Explanation

To calculate the volume strength of a 2N hydrogen peroxide (H₂O₂) solution, we will follow these steps:

### Step 1: Understand the relationship between Normality and Equivalent Weight
The volume strength of a solution can be calculated using the formula:
\[ \text{Volume Strength} = \text{Normality} \times \text{Equivalent Weight} \]

### Step 2: Calculate the Equivalent Weight of H₂O₂
The equivalent weight of a substance is defined as the molecular weight divided by the number of electrons transferred in a reaction. For hydrogen peroxide (H₂O₂), it can act as a reducing agent, and in reactions, it can release 1 mole of oxygen (O₂) per 2 moles of H₂O₂.
