You want to set up a series of voltaic cells with specific cell potentials. A Zn²⁺(aq, 1.0 M) | Zn(s) half-cell is in one compartment. Identify several half-cells that you could use so that the cell potential will be close to 

(a) 1.1 V and

(b) 0.50 V. Consider cells in which the zinc cell can be either the cathode or the anode.
