### Pt(s)

When is it necessary to write the Pt(s) in the cell diagram?

You would use an inert electrode such as Pt(s) in the case that there are no solid species given by a half-reaction.

A solid state conductor is necessary for the cells. When there isn't a solid given, Pt(s) is typically used and thus you must include it in the cell diagram.

When there's no solid already in the rxn. Both the anode and cathode needs a solid.

Pt(s) is generally used whenever a solid is not given to write the cell diagram for both the anode and the cathode.

Also, even if the equation gives you a solid, make sure it's a metal. If not, then you have to use Pt(s).

Can you use any other metals? I think the textbook might have used Au(s) before.

When a conductor is not present. Know that if there is a solid,it does not mean it is automatically a conductor, because some solids are salts,so the Pt will still be needed.

You need something for it to attach to (a solid). I'm not exactly sure why it has to be Pt though

Can it be written at the beginning of a cell diagram or does it always have to be in the end?

When there is no solid or metal present.
