Oxidation-Reduction Half Reactions
« on: September 12, 2015, 01:43:36 AM »
H2O2 + MnO4- + H+  :rarrow: Mn2+ + H2O + O2
I need help determining how to set up a half reaction. If there's already a thread explaining this, please point me to it. I'm new to the forum so I'm not sure where things should be.

First recognise what's being oxidised and reduced:
What oxidation state is Mn in MnO4 and Mn2+?
What oxidation state is O in H2O2? And O2?
