Cell Diagrams

Postby Gabriel Ordonez 2K » Sun Mar 08, 2020 7:20 pm

When are the instances that we have to add an inert solid to either end of the cell diagram? Is it always one or two ends of it?

We use a solid if there are no solids in the cathode or anode.

^ one thing to note though is that you should only add an inert solid if there is not a solid METAL at the cathode or anode side

You will commonly see an inert solid added to the cell diagram when the other components are in their aqueous form. You need the inert solid when there are no other solid metals in solution.

You add Pt typically to the cell diagram when there are no other metals present.

We use an inert solid when there is none present in the anode, cathode, or both. It varies from case to case, so it isn't always at one end or the other, or even both.

you add an inert solid usually if the reactants and products of a half reaction within a cell are of the same species or if it contains a gas

You only add a solid (usually Pt) to whichever side, if any, does not already have one. If the reaction for each side already contains a solid, do not add one.

When the other elements in the cell diagram is aq. state.

You add an inert metal when the species that is being reduced isn't a metal itself, or it's a nonconducting metal in which both the reactant and product are in aqueous form, instead of one in the solid phase and one in the aqueous.

You add a metal when there are no inert solids present in the reaction. Pt is commonly used and is an inert electrode in that it is a conducting agent

Can someone please give me a quick rundown on this or send a link to a resource? thx

When there's no solid metals present and it's only aqueous components, then you would add an inert metal.

You would add an inert solid if there are no solids in the reaction that could be used as a conductor. Usually Pt is added as the electrode.
