Question

salt bridge Zn(s) electrode Culs) electrode 1.0M Zn (a 1.0 M Cu (aq 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 zinc strip placed in a 1.0 M ZnCl2 solution, and the other has a copper strip placed in a 1.0 M CuSOA solution. The overall cell reaction is: Zn(s)Cu2+(aq)= zn2+ (aq ) Cu (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: Al- [AI]3+ (not [A+3), and Li [Lil+(not [Li]1 or [Li]+1). Do not use brackets for ncutral specics Anode half reaction: (aq) e (s) e Cathade half reaction: (aq) (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 copper electrode is positive and the zinc electrode is negative. Electrons flow from the zinc electrode to the copper electrode through the volt meter. Cations migrate from the 1.0M ZnCl2 solution through the salt bridge to the 1.0 M Cuso4 solution Cations migrate from the 1.0 M CuSO4 solution through the salt bridge to the 1.0 M ZnCl2 solution. The zinc clectrode is the anode and the copper clectrode is the cathode Anions migrate from the 1.0 M Cuso4 solution through the salt bridge to the 1.0 M ZnCl2 solution The zinc electrode is positive and the copper electrode is negative. Electrons flow from the copper electrode to the zinc electrode through the volt meter. Anions migrate from the 1.0 M ZnCl2 solution through the salt bridge to the 1.0M CuSO4 solution The copper electrode is the anode and the zinc electrode is the cathode
