### Pt(s)

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

### Re: Pt(s)

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.

### Re: Pt(s)

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

### Re: Pt(s)

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