Order of Cell Diagrams

Postby Isabella Sanzi 2E » Mon Feb 19, 2018 10:33 pm

So I understand that the anode reaction should be on the right side of the diagram and the cathode should be on the left, however, within the anode and cathode individually, what are the conventions for creating these diagrams? When do I use a comma vs. a | or when do I add Pt or another conducting metal? Also, does order matter in regards to each side -- for example does it matter if I write Fe3+|Fe2+ or Fe2+|Fe3+? Thanks!!

For cell diagram, within each half part, electrode and solids are written far away from the salt bridge, followed by liquid, gas and aqueous solution. Within each phase, orders are not strictly defined, but people tend to put in the order of reactant to product.

Use a comma when there is no difference in phase. If there is a phase separation, use a line.
