how do i show that the concentration of hydrogen pyroxide is proportional to the oxygen it produces?

Question

can you tell me how to carry out the experiment

Answer 1

Well, clevelandbrownsgirl2007 is close, but not quite correct. The balanced equation for the dissociation of hydrogen peroxide is:

H2O2 ===> H2O + ½O2

So, for every one molecule of hydrogen peroxide that dissociates, you get one oxygen ATOM released, or one-half of an oxygen MOLECULE released.

You can demonstrate this by collecting the oxygen gas that is generated by the decomposing peroxide: measure the starting concentration of your peroxide, then seal the container under a blanket of nitrogen. The nitrogen will not support combustion, so a burning splint put in the system will go outimmediately. Now wait a few days, and put the buringin splint under the cover -- it should flare up for a moment until the oxygen is exhausted, forming water. If you could collect the water and measure the quantity, and then measure the concentration of peroxide, you should be able to get a pretty decent mass balance (within experimental error).

Answer 2

The balance equation is...

H2O +O2 = H2O2

it takes, one mole H2O and one mole O2 to yield 1 mole H2O2.

These numbers are given by the balanced equation. There is no 1 in front of the molecules because it is understood.
