Standard Potentials

Because the Zn s Cu 2 aq system is higher in energy by 1.10 V than the Cu s Zn 2 aq system energy is released when electrons are transferred from Zn to Cu 2 to form Cu and Zn 2 Because the potential energy of valence electrons differs greatly from one substance to another the voltage of a galvanic cell depends partly on the identity of the reacting substances.
