I remember reading about the standard electrode potential (thats what I think it is called) and I recall the standard hydrogen cell where there is an acid as an electrolyte and a platinum .Do they use platinum as the electrode to compare with the other half cell as they dont react with an acid thus the el;ectrons must be coming from the other half cell.

of course an inert electrode such as Pt will be used. The electron exchange occurs between hydrogen gas and the hydrogen ions, not from Pt metal.

thanks thats what I thought.
