COPPER ELECTROWINNING: THEORETICAL AND PRACTICAL DESIGN 217 where Eeq is the equilibrium voltage, Eeq=Eo′when C ox(bulk) = C red(bulk) and E o′=Eo when activity coefficients are equal to one, see Equation [20]. An expression for the equilibrium potential is derived and shows Eeq to be close to the standard electrode potential and to vary
