Order in Cell Diagrams

Postby Shivangi_2J » Wed Feb 27, 2019 12:13 pm

when writing cell diagrams in which both species at the anode or cathode are aqueous solutions, does the order in which we write the aqueous solutions matter?
For example in the reduction reaction Ce4+ + e- --> Ce3+

does: [anode] || Ce4+, Ce3+ | Pt
mean somethingdifferent than:
[anode] || Ce3+, Ce3+ | Pt

Dr Lavelle gave a detailed explanation for how to write the cell diagram in this post:

He did not mention the sequence of the ions in the same phase, so I think both are fine! The more important things to take note of are probably included in his explanations already.

I think either way should work, however I like to write them in order of oxidation or reduction because it makes more sense in my head.

Both work as long as they're in the same state, and either one of them in aqueous form is placed next to the salt bridge.
