Cell Diagram and Pt(s)

Postby Nhi Vo 3A » Mon Mar 13, 2017 9:41 am

How do we know when to add the Pt(s) in our cell diagrams?

Pt(s) is added to a cell diagram when one or both of the elements being reduced/oxidized, is aqueous in both states. Then, the element needs a solid electrode so Platinum is used because it does not react and provides a surface for the oxidation/reduction to occur.

You add Pt(s) when at least one side of the cell does not have solid reactants. The Pt(s) functions as a nonreactive electrode when the reactants are all in solution

You add Pt(s) when the reactants are any other phase than a solid so that there is something that can transfer the electrons as it is inert and will not participate in the chemical reaction.

Do the ions go on the inside or outside of the cell diagram?
