Calculate the standard cell potential for each of the electrochemical cells in Problem 43.

Problem 43

Sketch a voltaic cell for each redox reaction. Label the anode and cathode and indicate the half-reaction that occurs at each electrode and the species present in each solution. Also indicate the direction of electron flow.
