Cell diagram

[Maria Solis Disc 1G]

When drawing a cell diagram, why is platinum or carbon i belive included in the diagram if it is not involved in the actual reaction.

[Jonas Talandis]

We include these typically when there is no solid involved on that side of the reaction. If there's no solid, there's usually no conductor to actually transfer these electrons so we use an inert one.

What doesn't get put in the cell diagram? Is it just solids and H2O liquid? Does H+ get put in the cell diagram?

there must be a solid in the reaction so if there isn't one we add Pt(s) in place

[Erin Kim 2G]

If one side of the reaction (anode or cathode) does not have a solid component, than Pt (a solid) must be added in order to have a solute.

[Nicole Garrido 2I]

To conduct electricity, move ions, the reaction needs electrodes to move them. So if there is no metal solid in the reaction there is no electrode. So platinum is used as a conductor.

[Kyither Min 2K]

There has to be a solid in the cell to transfer the electrons. Therefore, if the reaction itself doesn't have a solid or metal we add carbon or platinum.
