Electrochemistry - University of Denver

Cell potentials measured under standard-state conditions are represented by the symbol E o. The standard-state cell potential, E o, measures the strength of the driving force behind the chemical reaction. The larger the difference between the oxidizing and reducing strengths of the reactants and products, the larger the cell potential.

The electrical potential of a cell results from a competition for electrons. In a zinc-copper voltaic cell, it is the copper(II) ions that will be reduced to copper metal. That is because the Cu 2+ ions have a greater attraction for electrons than the Zn 2+ ions in the other half-cell. Instead, the zinc metal is oxidized.
