A solution containing equimolar amounts of NiCl2 and SnBr2 is electrolyzed using a 9V battery and graphite electrodes. What are the first products formed?
(A) Ni(s) at cathode, Cl2(aq) at anode
(B) Ni(s) at cathode, Br2(aq) at anode
(C) Sn(s) at cathode, Br2(aq) at anode
(D) Sn(s) at cathode, Cl2(aq) at anode
Standard Reduction Potential (V):
Ni2+(aq) + 2e – → Ni(s) –0.236
Sn2+(aq) + 2e – → Sn(s) –0.141
Br2(aq) + 2e – → 2Br –(aq) 1.077
Cl2(aq) + 2e – → 2Cl –(aq) 1.360
