4. Electrochemical cell Single electrode potential is a measure of tendency of an element to loose or gain electron when it is in its own solution. (measure of individual electrode contribution on the cell voltage) Standard electrode potential is a potential of a cell in which redox couple forms right hand electrode and left hand electrode is a standard hydrogen electrode and all species are at unit activity and 298 K. Pt (s) /H 2(g) (1 atm)/H + ( aq ) (1 M)//M n+ ( aq ) (1 M)/M (s) at 298K
