Question

A electrolytic cell similar to that shown in the figure above is constructed. The electronic device shown at the top of the figure is a power supply. One electrode compartment consists of a chromium strip placed in a 1.0 MCrCl3 solution, and the other has a silver strip placed in a 1.0 M AgNO3 solution. The overall cell reaction is:

Cr3+(aq) + 3 Ag(s)  Cr(s) + 3 Ag+(aq)



(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)
