Reduction involves gain of electrons, so the tendency of an electrode to gain electrons is called its reduction potential. The equilibrium potential difference between the metal electrode and the solution surrounding it is called the electrode potential. It is also defined as the tendency of an electrode to lose or gain electrons.If we are reducing copper 2+ to solid copper, the standard reduction potential is +.34 volts. If we are reducing zinc 2+ to solid zinc, the standard reduction potential turns out to be -.76 volts. The more positive value, the more likely the substance is to be reduced, so obviously +.34 is more positive than -.76.Redox chemistry plays an enormous part in our daily lives in today’s electronic world, particularly in the use of smartphones, which rely on the latest redox cell technology.
