How do you balance the equation IO3(-) + 3I(-) --> I3(-) by using half reactions?
oxidation: 3I(-) --> I3(-) +2e-
reduction: + 3I(+5) --> I3(-)
after balancing the half reactions, i know that i need to add oxygen to the right, and then balance by adding hydrogens to the left..
but how to i get from what point i'm stuck at???
