1. The problem statement, all variables and given/known data 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 2. Relevant equations 3. 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!
