Volume Strength of 1.5N H2O2 Solution

What Is the Volume Strength of 1.5N H₂O₂ Solution?

Volume Strength

The term used to represent the concentration of hydrogen peroxide in the form of volume of oxygen that can decompose to generate water and oxygen gas is volume strength or percentage strength of hydrogen peroxide.

The decomposition reaction of hydrogen peroxide is as follows

Decomposition reactions are the breakdown of chemical species into simpler components. Typically, decomposition reactions necessitate the addition of energy.

2H₂O₂  2H₂O + O₂

Let’s calculate the volume strength of the hydrogen peroxide;

From the given,

Normality of hydrogen peroxide = 1.5

Molar mass of hydrogen peroxide = 34g

Equivalent weigth of hydrogen peroxide = 34/2 = 17g

 Strength of H₂O₂ will be;

Strength  of H₂O₂ = Normailty of solution Equivalent weight

= 1.5 17g

= 25.5 g

From the decomposition of reaction of hydrogen peroxide,

2 moles of H₂O₂ produce two moles of water;

At NTP the volume is 22.4 L

 2 moles of H₂O₂  = 2 34 = 68 g

Hence, 

68 g H₂O₂   22.4L

25.5g H₂O₂ ?

Therefore, the volume strength of 1.5N hydrogen peroxide solution is 8.4L.
