10.2 Batteries and Electrolytic Cells
Because the potential energy of valence electrons differs greatly from one substance to another, the voltage of a battery depends partly on the identity of the reacting substances. If we construct a battery similar to the one in part (a) in Figure (PageIndex{1}) but instead of copper use a strip of cobalt metal and 1 M Co 2 +, the measured voltage is not 1.10 V …
