How do you balance disproportionation redox reactions?
You balance them stoichiometrically, and in fact you follow the same procedure of separate redox processes for oxidation and reduction.
Chlorine gas is known to disproportionate to chlorate and chloride ion:
So mass and charge are balanced in the half equations. All I have to do is simply combine them in the usual fashion to remove electrons:
Now all I have done here is to treat this like a normal redox equation. I considered the oxidation reaction, and the reduction reaction SEPARATELY utilizing electrons as virtual particles of convenience, and I add the oxidation and reductions reactions appropriately to eliminate the electrons.
Can you balance the reaction of the interhalogen compound,
