A voltaic cell similar to that shown in the figure above is constructed. The electronic device shown at the top of the figure is a volt meter. One electrode compartment consists of a aluminum strip placed in a 1.0 M Al(NO3)3 solution, and the other has a nickel strip placed in a 1.0 M NiSO4 solution. The overall cell reaction is:2 Al(s) + 3 Ni2+(aq) 2 Al3+(aq) + 3 Ni(s)(a) Fill in the information necessary to complete the half reactions that occur in the two electrode compartments. Use the lowest-possible whole-number coefficients. To input an ion surround the ion's element symbol with square brackets and put the ion's charge to the right like this: Al3+ = [Al]3+ (not [Al]+3), and Li+ = [Li]+ (not [Li]1+ or [Li]+1). Do not use brackets for neutral species.Anode half reaction: (s) (aq) + e-Cathode half reaction: (aq) + e- (s)(b) Figure out which electrode is the anode, which is the cathode, the signs on these electrodes, the direction in which the electrons flow through the volt meter, and the direction in which cations and anions migrate through the salt bridge and solutions. Use this work to pick all of the statements from below which are true. The nickel electrode is positive and the aluminum electrode is negative.The nickel electrode is the anode and the aluminum electrode is the cathode.The aluminum electrode is positive and the nickel electrode is negative.Electrons flow from the nickel electrode to the aluminum electrode through the volt meter.Anions migrate from the 1.0 M Al(NO3)3 solution through the salt bridge to the 1.0 M NiSO4 solution.Electrons flow from the aluminum electrode to the nickel electrode through the volt meter.Cations migrate from the 1.0 M NiSO4 solution through the salt bridge to the 1.0 M Al(NO3)3 solution.The aluminum electrode is the anode and the nickel electrode is the cathode.Cations migrate from the 1.0 M Al(NO3)3 solution through the salt bridge to the 1.0 M NiSO4 solution.Anions migrate from the 1.0 M NiSO4 solution through the salt bridge to the 1.0 M Al(NO3)3 solution.
