Cell Diagrams (Using Platinum)

Postby Nicholas Le 4H » Fri Mar 01, 2019 5:03 pm

When do we use platinum metal in the cell diagram, and why do we use platinum as the metal?

We use platinum in a cell diagram when either the cathode or the anode lacks a solid that can be used to conduct electrons from one side of the beaker to the other. This is because platinum is inert and will not react with anything else in the reaction.

But why in the textbook solutions there occasionally is platinum on both sides of the salt bridge, even though one side has a solid?

Platinum is used when there isn't a conducting solid. So in the textbook, there can be platinum on a side with a solid because that solid isn't a conductor. Platinum is used because it is inert and won't react.

You use Platinum(s) when there is no conducting metal on either the anode/cathode side of the reaction.

Platinum is used when there is no conducting metal on either or both sides of the redox reaction. Another used electrode can be graphite, but platinum is most common in the textbooks.

We add in Pt on the ends of a cell diagram when there are no solid metals on either side of the cell diagrams.

A metal is used as a cathode or anode to conduct electricity so a reaction without a metal would not transfer ions. To make the circuit work for solutions with aq or gas reactants platinum needs to be added as a conductor.

Why do we use Platinum instead of some other metal? I know we can use C(graphite) too.

We use platinum because It is highly inert and is great conductor therefore it is used when there are no present solids

We decide to use platinum if there is not already a metal on one side of the diagram.
