In aqueous solutions, redox potential is a measure of the tendency of the solution to either gain or lose electrons in a reaction. A solution with a higher (more positive) reduction potential than some other molecule will have a tendency to gain electrons from this molecule (i.e. to be reduced by oxidizing this other molecule) and a solution with a lower (more negative) reduction potential will have a tendency to lose electrons to other substances (i.e. to be oxidized by reducing the other … WebFor example, if copper two plus is reduced by two electrons to form solid copper, the voltage for this half reaction, or the Standard Reduction Potential, is equal to positive 0.34 volts. And for the reduction of zinc two plus ions by two electrons to form solid zinc, the Standard Reduction Potential is equal to negative 0.76 volts.
