When do you include platinum in the cell diagram?

When the questions states that the electrode component of the cell diagram uses Platinum. In the cell diagram it is generally written as the outermost component of the electrode in the diagram.

Example: Hydrogen electrode constructed with Platinum
Right electrode: H+(aq)|H2(g)|Pt(s)
Left electrode: Pt(s)|H2(g)|H+(aq)

The textbook states that you include an inert electrode such as platinum when the electrode reaction does not include a conducting solid as a reactant or product.

Whenever there’s no elements w the (s) subscript. That’s the element you add it to because Platinum is a non reacting element in these reactions.
