Using commas in cell diagram

[MadisonFuentes1G]

When do we use commas in a cell diagram as opposed to using a straight line?

[Dimitri Speron 1C]

straight lines indicate that they are in the same phase in the same beaker. A straight line indicates that they are in different phases. (when used to show the different between oxidized and reduced states)

[Grace Kim 1J]

You use a single line to separate chemicals in different phases. However, if you have multiple chemicals in the same phase (for example, 2 aqueous solutions) you can separate them with a comma. A double line, which represents a salt bridge, can be used to separate the cathode and anode.

Hope this helped!

[Aarti K Jain 1L]

A comma is used when both the oxidized species and the reduced species are in the same phase (usually, both are aqueous) for the same half-reaction. A straight line indicates a phase change between the oxidized species and the reduced species in the same half-reaction.
