Predict how the Ecell for the copper/zinc cell in part 1 would change (increase, decrease, remain the same) if:
1. Cu (s) in 0.1 M CuSO4 (aq) and Zn (s) in 0.1 M ZnSO4 (aq)
a. the concentration of the anode solution were changed to 1 M.
b. the concentration of the cathode solution were changed to 1 M.
c. a larger piece of metal were used.
2. Calculate the Ecell for the copper concentration cell in part 2 if 0.01 M CuSO4 was used instead of 0.1 M CuSO4.
