4. In part V, you will expose your cell to direct sunlight and indirect sunlight (i.e., shade).
How do you expect the cell’s output voltage to when the cells are in a shaded area to compare to their voltage when they are directly exposed to the sun? Explain your answer.

A concentration cell containing aqueous solutions of Cu(NO3)2 and solid copper metal is constructed so that the Cu2+ ion concentration in the cathode half-cell is 0.66 M. What is the concentration of the Cu2+ ion in the anode half-cell if the cell potential for the concentration cell at 25 oC is 0.034 V?
