Let us consider an example of 1.5N hydrogen peroxide solution to understand the volume strength of the H2O2 solution.
1.5 N = 1.5 g equivalent weight in 1 L solution.
N = Weight / Equivalent weight for hydrogen peroxide
Equivalent weight of hydrogen peroxide = 17 g
∴ 1.5 = Weight /17
Weight = 1.5 X17
Weight of H2O2 = 25.5 g
Now, from the equation we know that 68 g of H2O2 gives 22.4 L of Oxygen.
Therefore, 25.5 g of Hydrogen peroxide gives
⇒ 22.4 X 25.5/68
= 8.4 L
