Cell Diagram

In a cell diagram, do we always use Platinum if nothing else is stated to be used?

Platinum is the most common electrode that you'd use if you need a solid electrode for a cell, so I'd assume that you can use it anytime you need to.

Yes, if we only have (aq) or (g) at one side and no electrode told.

Yes, you would place platinum electrodes in the sides with no solid electrodes, but other electrodes would be preferred depending on what's in the solution like iron electrodes are preferred if the solution contains iron and so on.

Yes, platinum should be used when you do not have a solid in the half-reaction. It is a non-conductive metal, so it is usually the best choice

Yes. Since Pt(s) is an inert metal, it is commonly used in the absence of a conductive solid.

yes, we use pt for solid if there is no other solid stated

You can use platinum or graphite. Most people will probably use platinum if nothing else is stated in the question.

If we have two molecules that are both solid, do we still have to use Pt or any other inert metal since they are in the same phase.
