A dilute solution of H2O2 is labelled as 20 volume.its percentage strength id

Answer 1

Hi, please consider the answer given below;

The answer is 6 %.

We go as follows, When a dilute solution of hydrogen peroxide, H2O2 is labelled as 20 volume, what it implies is that 1 litre of H2O2 solution would produce 20 litre of Oxygen.

Thus may be based on the equation 2H2O2 ------> H2O+ O2

Thus we say that 20 volume of H2O2

gives 68/22400 x 20 =  0.06 g

which translates to 6%.
