Question

What do you mean by 15 volume H2O2 solution

Answer 1

Heya !

____________________________________________________________

→As the Question is about H2O2 , firstly let's know what is H2O2 ?

=> H2O2 is Hydrogen Peroxide . It is a pale blue coloured liquid - viscous than water.

=> Decomposition of Hydrogen peroxide -

→ H2O2 ---------------> H2O + O2

★Lets move to the Question -
==========================


=> What do you mean by 15 volume H2O2 solution ?

=> Strength of H2O2 is measured as Volume % . 15 Volume of H2O2 means that 1 Litre of solution will give 15 litre of Oxygen at NTP.

Answer 2

10V H2O2= 1 litre of H2O2 gives 10 L of O2.

Note - Normality of H202= Volume strength/5.6

Molarity = Volume strength /11.2
