When to add Platinum

Postby Noe BM 1J » Sun Mar 01, 2020 10:43 pm

When do you add platinum to the cell diagram of a redox reaction, and on which side does it go?

You add platinum when there's no solid in either the anode or cathode of the cell (like if there's only an aqueous solution). You add it to the side without a solid.

You add platinum or another inert electrode when both oxidized and reduced species are in the same solution. It is easy to tell when you look at the phases in the equation, since the electrode is always a solid, so whenever one side of the cell doesn't have a solid you need to add an inert electrode like platinum.

I believe you add platinum to a cell diagram when the anode and/or the cathode need a solid conductor.

How do we know/tell if the anode or cathode needs a solid conductor?

We know we do based on the phases of the molecules. If it's just aqueous phases, then you'll definitely need one. Even in cases where there is a metal but it's not in a solid phase (such as Fe (aq)) you will need to add platinum. Sorry for the late response.

Add platinum or another inert electrode when there is not a phase change or the oxidized and reduced things are in the same soluttion in the cathode or anode.

Platinum is usually included when there is no electrode available to drive the reaction.

And you can add platinum because it is an inert metal and won't react with anything causing values to change
