Writing Cell Diagrams

Postby GavinAleshire1L » Tue Feb 26, 2019 6:08 pm

When do we know to include an inert metal (i.e. Pt) in our cell diagrams?

An UA told me you don't need it when you have a metal present on both sides of the salt bridge. However, if one or both sides lacked a metal, then you would insert Pt (s) on the side(s) without a metal

Yes just like Joanna said above, you add an inert metal to act as an electrode when there isn't already a metal on both sides.

We include an inert electrode when either the anode and cathode are either gas/aqueous and both the reactants and the products are in that same phase.
So for example,
A hydrogen( gas ) electrode would require a platinum electrode.
