commercial hydrogen peroxide contains small amounts of organic compounds that are added to stabilize it. If these compounds react with permangate(what was used to titrate) how would this affect your titration results?

ok well here is what I got.

when titrating it would react to give you an inaccurate volume of permangate needed to titrate the hydrogen peroxide because it would be more stable, am I right? or is there more to whats going on

The key part of the question is that the organic compounds react with the permanganate.  In this titration, you calculate the amount of H2O2 based on the amount of permanganate which reacts during the titration.  So, if permanganate reacts with the H2O2 and with the organic compounds, how will that affect your calculations of the amount of H2O2 in the sample?

Seems is if you need to figure out if the organic compound will react with the titrant and make the endpoint with less titrant than it should be, or it will slow down the final reaction you will wind up with more titrant in the solution.
