Question

what do you mean by 15 volume h2o2 solution

Answer 1

Hi mate,

Ur Answer is here,


The strength of H2O2 is defined by two ways:
1.) Percentage strength : This tells about the percentage of pure hydrogen peroxide in the solution. Like, 3% H2O2 means, 3mL of pure hydrogen peroxide is present in 100 mL of solution.
2.) Volume strength : This tells about the release of oxygen by 1 mL of hydrogen peroxide solution.  Like, 10 volume of ​ H2O2 means, 1 mL of this solution will release 10 mL of oxygen. 15 volume of ​ H2O2 means 1 mL of this solution will release 15 mL of oxygen and so on.

Answer 2

$15$ volume $\[{H_2}{O_2}\]$ solution means $\[1\,ml\]$ of this solution will give $\[15\,ml\]$ of oxygen.

Explanation:

• The strength of a solution gives the amount of solute present in oen litre of the solution.
• There are two ways to determine the strength of Hydrogen peroxide ($\[{H_2}{O_2}\]$). They are:

1. Percentage strength
2. Volume strength

• Percentage strength gives the amount of hydrogen peroxide present in $\[100\,ml\]$ of solution.
• On the other hand, volume strength refers to the volume of oxygen released at N.T.P when $\[1\,ml\]$ of the sample of hydrogen peroxide is decomposed.
• Therefore, $15$ volume $\[{H_2}{O_2}\]$ solution means $\[1\,ml\]$ of this solution will give $\[15\,ml\]$ of oxygen.
