2.4 Electrode, Electrode Potential and Electrochemical Series
The main idea is that different metals have different tendencies to lose or gain electrons. When a metal is placed in water or a solution of its ions, a dynamic equilibrium is established between the metal atoms and their ions. This equilibrium creates a potential difference (voltage) between the me
