Adding Pt(s) to cell diagram

Postby Gillian Ward 1F » Fri Mar 15, 2019 10:07 am

When do we add Pt(s) to a cell diagram?

Add Pt(s) to a cell diagram on the side that does not have a conducting solid. So each side must have a solid that is a conductor (usually look for metals).

Are there any exceptions to this?

Not sure about exception, but one side of the cell diagram must have a conducting metal solid

A cell always has to have a conducting metal. If the reactants and products of the redox reaction are all aqueous, the electrons will not be transferred. In these scenarios you have to have an inert (one that does not take part in the reaction) electrode to attract the electrons/create a current.

The one exception to this that Dr. Lavelle mentioned was mercury since it is a liquid at room temperature. Though it is a liquid, it can still conduct electrons and act as an electrode.
