Homework Statement



1. Explain why the following chemical reaction would not be effective to determine [Fe2+] in a given solution.

Fe2+ (aq) + H2O2 (aq)-> Fe3+ (aq)+ H2O(l) | in acidic solution

Homework Equations





The Attempt at a Solution



Hello:

I am thinking that there may be a lack of colour change to indicate the stiochiometric endpoint of the redox reaction. I know that hydrogen peroxide and water are both clear and colourless in solution.

However, I do not know the colours of Fe2+ and Fe3+ in solution.

Thank you in advance!

Endpoint detection can be done with some instrumental method, so it should be not a problem (although listing it won't hurt). However, what do you know about hydrogen peroxide stability?
