Re: Cell Diagram
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.

Re: Cell Diagram
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.

Re: Cell Diagram
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

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

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

Re: Cell Diagram
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.
