Inert conductor

[Dang Lam]

How do we know when to include an inert conductor into our cell diagram?

[Nickolas Manipud 1C]

You include it when a half-cell does not have any other solid or liquid that is part of the half-reaction to conduct electricity.

[Jason Liu 1C]

I think you need an inert conductor when the reactants and products of the half reaction are both gases or solids because you need a solid to transfer the electrons to make the half reaction occur.
