I have been using as a rule that the anode compartment contains thespecies with smallest standard reduction potential, but thefollowing question that does not seem to work. Here is thequestion
What reactions take place at the cathode and the anode when each ofthe following is electrolyzed
(c) molten MnI2
The cathode
Mn(2+)+ 2e- -> Mn E(Standard)=-1.18V
The anode
2I- -> I2 + 2e- E=-.54V
How do we know what is Cathode and Anode in this case?
