Platinum

Postby Rhea Shah 2F » Sun Mar 08, 2020 8:03 pm

When do you know when to add platinum or another solid element to the cell diagram?

You add platinum as an electrode when the reactants/products are not conductive solids.

Platinum is added to any side of a cell that is missing a solid conductor. This could be both sides, one side, or neither side depending.

You add platinum or another inert electrode when you don't have a solid electrode in the cell diagram.

What defines a solid conductor?

Add platinum when there isn’t a solid electrode already present in the reaction.

When there is no solid given in the cell diagram or reaction, you can always use platinum as the metal.

A solid conductor is a metal in solid state.

If you have an ion-gas reaction or if you do not have a solid state metal/conductor on that part of the galvanic cell, then you need to include some kind of conductor like Pt(s)! Platinum is only one of them, but it's probably the most common one to use.

You add platnium, or another solid metal conductor, whenever there is no solid on either side of the cell diagram.

You add platinum when there is no other solid metal in the oxidation reaction or reduction reaction.
