A voltaic cell similar to that shown in Figure 20.5 in the textbook is constructed. One electrode compartment consists of an aluminum strip placed in a solution of Al(NO3)3, and the other has a nickel strip placed in a solution of NiSO4. The overall cell reaction is 2Al(s)+3Ni2+(aq)→2Al3+(aq)+3Ni(s)
