### Salt bridge

How do I know when to include the salt bridge in a cell diagram?

I think the salt bridge is always included in the cell diagram as || to separate the anode on the left from the cathode on the right. Since a proper cell should always have a salt bridge to function correctly and avoid charge buildup, the salt bridge is an essential part of the cell diagram, which outlines the setup of the cell.

What I mean is how do I know when the inert electrode is Pt or Ag or nothing?

You will use the inert electrode such as Pt when you need a metal to carry the e- from the anode to the electrode. For example, if you have a gas and an aqueous, then you would use the inert electrode. You would also use it if you had all aqueous.
