Platinum in Cell Diagram

Postby Ryan Danis 1J » Wed Mar 13, 2019 1:44 pm

When and why do we add platinum to a cell diagram?

Platinum is written in the cell diagram to indicate that a solid platinum electrode is needed to recreate a working cell. This is needed when the anode or cathode of a cell doesn’t have any conducting substances in its composition. The platinum conducts the charge to create a current.

basically if you notice in your cell diagram that there is no solid/conducting component, you add platinum to either the cathode, anode, to both depending on which is missing a conductor.

in general, if there is no solid in the cell diagram you need to add platinum

We add Pt(s) if the reaction has no conducting (metal) solid.

All of the above answers look good, but for this class, my TA said that we only need to add it if there is no conducting metal in the equation the only exception is Hg liquid

Also I think Graphite a non metal can conduct electricity

Platinum is an inert conductor added in order to conduct a charge. You add platinum when no other inert solids are able to perform conduction in the cell.

Pt is used as a conducting metal when your cell diagram doesn't contain a solid. And it is always added to the outside of the diagram
