Cell Diagram

[melissa_dis4K]

I know that when we have two aqueous we write the one with the higher oxidation state first, but what if they have the same oxidation state? Example: S2O8^-2 and SO4^2-. Thanks!

I don't think it matters which one you write first, however, make sure to use a comma since they are in the same phase.

[Aurbal Popal]

I could be wrong, but I think the oxidation number for S in S2O8^(2-) is +7 and the S in SO4^(2-) is +6. I drew it out but I think something is off... so I could be wrong.

Just to confirm, does order matter when drawing a cell diagram (with regard to on the anode or cathode side, does it matter which species goes first?)

[Manu Vohra 1L]

For cell diagrams it usually doesn't matter which aqueous species comes first, however, you do want to make sure of a few things:
--the electrodes are always on the ends
--cathode is always on the right and and anode always on the left.
--aqueous ions (H+ and OH- included) are always closest to salt bridge
