Platinum is the most common electrode because it is an inert conductor. It will not react with and affect the redox reaction.

If you need to write a cell diagram and a half-reaction doesn't have a solid, you can use platinum.

Pt is used if the given redox reaction has only aqueous solutions and no solid conductor used in the reaction within a galvanic cell.

It is basically a way for electrons to enter a solution of ions. For example, if you were reducing Fe 3+ tp Fe 2+ (both of which are ions), you would use a platinum electrode to transfer electrons to the Fe 3+ to reduce it to Fe 2+. I hope that this helps!

It's a common electrode because it is inert and doesn't interfere with the redox reaction
