Cell Diagram

Postby Ryan Fang 1D » Tue Feb 20, 2018 8:41 pm

When you do a cell diagram, when do you use commas (,) and when do you use slashes (|)?

I think if they are in the same state then you can use commas. However, whenever there is a solid and another state involved, you have to put the line.

Commas are used to separate like states of matter on the same side (cathode or anode), while slashes separate different states of matter on the same side. For instance,
Fe 2+ (aq), Fe 3+ (aq) || Ag + (aq) | Ag (s)
where the two iron ions on the anode side are like states of matter, and the silver ion and silver solid are on the cathode side but are different states of matter

The single line (|) indicates the interface of two different states of matter (within each respective electrode) whereas commas in the cell diagram are used to separate species (within each respective electrode) with the same states of matter; often times, these species are dissolved as ions in an aqueous solution.
