 P: 614 1. The problem statement, all variables and given/known data 2. Relevant equations 3. The attempt at a solution I always thought you put the electrolyte of one half cell on one side and the other electrolyte on the other side The answer given is C. But this includes VO2+ which is not in the initial eqn on the RHS?

 Quote by borek try to split the reaction into half reactions.
V3+ + H2O = VO2+ + 2H+
VO2+ + H2o = VO2+ + 2h+

Well V3+ is oxidised (reducing agent) and VO2+ is reduced (oxidising agent).
I think you are supposed to put the stronger reducing agent on the left side?

Isn't it what they did?

...of course....I think I just get confused between VO2+ and VO2+.

...I guess though this will help me in exams as I will be more aware of what is going on....thanks for helping me :)
