Make a schematic diagram of a cell for each of the following cell reactions. Indicate on the diagram the anode, the cathode, the direction in which the anions and cations migrate through the cell and the salt bridge, if any, and the directions in which the electrons migrate through the external circuit. Calculate E° for each cell.
