Notation of Species

[Chloe Alviz 1E]

When would we use a comma versus a single line between the reactants and products?

[Jacob Puchalski 1G]

You use a single line to differentiate between phases. If they're both in the same phase then you list them using a comma.

It's not so much between the reactants and products but rather in cell diagrams to denote what species exist in each cell (the anode/cathode). So like it has been said, the single lines denote the different phases they exist in. If they are the same (like aqueous) then they have a comma between them.

Hi Chloe,

The single line denotes that the two species are in different phases (e.g. one is a gas while the other is aqueous). A comma is used if they are in the same phase (e.g. both are gases). I hope this helps!
