the half-reactions that occur at the cathode and the anode, and. the standard cell potential (0.267 V) Practice Exercise 1 (20.7) Consider three voltaic cells, each similar to the one shown in Figure 20.5. In each voltaic cell, one half-cell contains a 1.0 M Fe(NO3)2(aq) solution with an Fe electrode. The contents of the other half-cells are as ... ................
