Q. 39

Calculate the strength of 5 volume H2O2 solution.

Answer :

We know, molar mass of H2O2 is 34gm. According to this reaction, 2 moles of peroxide is involved, so mass becomes 68gm.


Also, we know that 1mole of any gas occupies a volume of 22.4L at NTP.


Now, 5 volume H2O2 solution means that 1 L of 5 volume H2O2 on decomposition gives 5L of O2 at NTP.



So we can see from the reaction that, from 22.4L at NTP, we get 68gm H2O2.


Now to get the required 5L of O2 at NTP, we need () gm H2O2


= 15.179gm


But we know that 5L of O2 at NTP is produced from 1L of 5 volume H2O2 , as we have to find strength of 5 volume H2O2


Strength of H2O2 in 5 volumes of it is 15.179gm/L


Percentage strength = ()%


= 1.518%
