Cell Diagrams

Postby Shimei_2F » Sun Mar 01, 2020 8:03 pm

When we write cell diagrams, and there are two ions ex: Fe2+ and Fe3+ both in aqueous solution. I know you don't separate it with the line (|) and instead, you separate it with a comma. But does it matter what order I write them in? Can I write them as either Fe2+,Fe3+ OR Fe3+,Fe2+?

The only order that matters is anode on the left and cathode on the right, and having aqueous next to salt bridge.

I am pretty sure you can write it either way as long as you follow the conventions for writing out a cell diagram.

I don't think it matters in what order you write them as long as you place a comma in between because of the similar phases.

Why does it matter to have aqueous next to the salt bridge?

Put the solids on the outsides, but other than that there is no convention for the order when there is a comma

It shouldn't matter what order you write Fe2+ and Fe3+ in because they are in the same phase.
