Question

Magnesium, the element, is produced commercially by
electrolysis from a molten salt (the “electrolyte”) using a
cell similar to the one shown here. (a) What is the most
common oxidation number for Mg when it is part of a salt?
(b) Chlorine gas is evolved as voltage is applied in the cell.
Knowing this, identify the electrolyte. (c) Recall that in an
electrolytic cell the anode is given the + sign and the cathode
is given the – sign, which is the opposite of what we see
in batteries. What half-reaction occurs at the anode in this
electrolytic cell? (d) What half-reaction occurs at the cathode?
