Part A) Electrolysis is performed on a mixture of CuBr(l),AgBr(l), MgBr2(l), and NiBr2(l). Which of the following is producedat the cathode?
| A) Cu(s) |
| B) Ag(s) |
| C) Mg(s) |
D) Ni(s) Part B)You are given some ferrous iodide, FeI2 , and are askedto extract the iron through electrolysis. What can be said aboutthe merits of molten versus aqueous FeI2 ? You are given some ferrous iodide, \rm FeI_2, and are asked toextract the iron through electrolysis. What can be said about themerits of molten versus aqueous \rm FeI_2? | A)You'll have to perform electrolysis on the molten saltbecause you can't get iron metal from electrolysis of the aqueoussolution. | | B) You'll have to perform electrolysis of the aqueous solutionbecause you can't get iron metal from electrolysis of the moltensalt. | | C) Electrolysis of either the molten or aqueous salt willproduce solid iron. | D) Electrolysis will not produce solid iron regardlessof whether the salt is molten or aqueous. Part C) For which of the following aqueous salts willelectrolysis produce hydrogen gas and oxygen gas? Checkall that apply. | A) NiI2(aq) | | B) NaF(aq) | | C) NiF2(aq) | | D) NaI(aq) | | E) CuBr(aq) |
