We are asked for the half-reaction that occurs at the anode in this electrolytic cell.
We’re given the following electrochemical cell:
Since a voltage source is given, this is an electrolytic cell, where a nonspontaneous process is occurring.
Since the process is nonspontaneous, an outside energy source provides energy for it to occur.
Magnesium, the element, is produced commercially by electrolysis from a molten salt (the "electrolyte") using a cell similar to the one shown below.
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?
