Cell Diagram Order

Postby Jonathan Pai 2I » Sun Feb 24, 2019 9:43 pm

In a cell diagram, knowing that the anode is the left side and cathode is the right side, on each respective side, does the order of the substances matter?

For example, is there a difference between these,
Zn/Zn2+//Ni2+/Ni versus Zn2+/Zn//Ni2+/Ni

You put the substance with the highest oxidation number in the couple in the middle of the cell diagram. So, for this problem, you would do Zn/Zn+2//Ni2+/Ni

If I remember right, Lavelle said it doesn't matter but just to be safe I think putting the one with the highest oxidation number in the middle would be better. I'm not a hundred percent clear tho. Can someone go ask Lavelle or a TA?
