Standard reduction potentials for zinc(II) and copper(II) The standard reduction potential for a substance indicates how readily that substance gains electrons relative to other substances at standard conditions. The more positive the reduction potential, the more easily the substance gains electrons. Consider the following: Zn2+(aq)+2eāāZn(s),Cu2+(aq)+2eāāCu( s), Eāred=ā0.763 V Eāred=+0.337 V
