How do you know whether or not to add Pt(s) when writing a cell diagram from being given two half reactions?

If the states of matter in either the cathode or the anode are all (aq), (l), or (g), then we add a solid electrode (Pt(s) is a common one to remember, but there are others).

If a solid (s) does not exist on one of the sides of the salt bridge (remember: anode || cathode), then yes, you can insert Pt(s).

Hope this helps!
