Cell Diagram Order for Same Phases

Postby Christina Cen 2J » Thu Feb 22, 2018 2:19 pm

When there are 2 elements in the same phase in a cell diagram separated by a comma like in 14.17 with
Pt(s)|Fe3+(aq), Fe2+(aq)||H+(aq), MnO4-(aq), Mn2+(aq)|Pt(s), how do you know which element comes first within the series of commas?

The elements in the anode are to the left of the salt bridge and the cathode on the right. From there, I believe each side is written in order of reactants to products.

I put it in order of the reactants, products
I am not sure if this is completely right but I have gotten the same answers so far

I asked my TA and he says it doesn't matter what order they are in if they are the same phase.

I think Lavelle prefers reactants listed before products, but I don't expect this to be graded too strictly.
