Splitting Redox Reactions

Postby Kaelie Blanes-Ronda 2L » Thu Feb 15, 2018 4:36 pm

How do you know where to split the reaction into half reactions? I know that a part is oxidized and the other is reduced but what about the other molecules that don't change signs?

The other molecules whose oxidation states remain the same throughout the reaction are spectators and don't have to be written in the final reaction.

The spectator ions get cancelled out anyway when you go from the ionic reaction to the net ionic reaction, I think. I don't think we need to know that for the test, but they cancel out anyway and don't matter.
