platinum

should we always use platinum for our cell diagram if we are not given a solid metal in the reaction?

[Amy Pham 1D]

Yes, when there is no specification, you use platinum as your inert conductor acting as a electrode to transfer electrons in the cell.

[Leslie Almaraz 4G]

yes because there must be a solid conductor in each of the reactions. make sure to indicate this in the cell diagram

[Manav Govil 1B]

You don't have to use platinum, but platinum is the best solid conductor to use for this class. There are other solid conductors out there that can be used in these reactions, and if the question wants you to use them, they will provide the data for them.

The purpose of platinum is to act as a conductor to transfer the electrons.
It is used, when there is no conducting metal, so, YES, if we are not given a metal, but aqueous solutions, we will use platinum.

[Hannah Pham]

Yes, you use platinum if no metals are given as your conductor.
