Laboratory Chemisry Question - Redox Reaction

[vertciel]

Homework Statement

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

Fe²⁺ _(aq) + H₂O_{2 (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?
