Question
12- An electrochemical cell is composed of pure copper and pure cadmium electrodes immersed in
solutions of their respective divalent ions. For a 6.5 × 102 M concentration of Cd²+, the
cadmium electrode is oxidized, yielding a cell potential of 0.775 V. Calculate the concentration
2+
of Cu ions if the temperature is 25°C.
