What is the difference between a comma and a vertical bar? I don't know when to use which when writing a cell diagram. Thank you.

I think you're supposed to use the vertical lines when creating cell diagrams.

I believe you use a comma when the species are in the same phase or state - I Fe^3+ (aq), Fe^2+ (aq) I -
and a vertical bar when there is a change in the states - I Zn(s) I Zn^2+ (aq)

The bar indicates a separate reaction/solution. A TA said the comma means it's in the same solution.
Hope that helps.

A single vertical line separates species that are in different phases. A double vertical line represents a salt bridge. A comma indicates that the species are in the same phase.
