5. An electrochemical cell was made by dipping a Cu wire and a saturated calomel electrode an aqueous 0.1500 M CuSO4 . The Cu wire was attached to the positive terminal of a potentiometer and the calomel electrode was attached to the negative terminal.
A. Write a half-reaction for the Cu electrode:
B. Write the Nernst equation for the Cu electrode and calculate the Cu half-cell voltage (assume T = 298 K, P = 1 atm).
C. What is the cell voltage for the electrochemical cell?
