If acidic H2O2 is mixed with Fe^2+, which reaction occurs: the oxidation of Fe^2+ to Fe^3+ or the reduction of Fe^2+ to Fe? Give the balanced redox reaction for each possibility and explain your reason for selecting the reaction which will occur. Assume standard solution concentrations. For a) I have: red: H2O2 + 2H+ + 2e- ---> 2 H2O E=+1.78 V oxi Fe2+ ----> Fe3+ + e- E=-0.77V Ecell = 1.01V I'm stuck on b) but for the explanation I...
