Platinum and Granite

Postby Lizette Noriega 1H » Tue Mar 03, 2020 5:01 pm

When do we know to use Pt(s) or C(gr) as our solid in cell diagrams?

We use platinum and graphite as the electrode in our cell diagrams when there are no conducting solids present for the given half-reaction.

But what is the difference between the two? How do you know when to use one over the other?

I suggest always using platinum because using granite is not common. If we have to use granite, I feel like we would be specifically told to do so.

Use platinum since it is more common. And use it when there are no conducting solids or if the species reduced and oxidized are in the same solution.
