We have molten that is electrolyzed, and we need to write the reactions that are occurring at the cathode and at the anode.
First, let us define some terms:
Galvanic cell is a device in which spontaneous redox reaction occurs, and as a result, electricity is produced.
Electrolytic cell is a device in which electricity is used in order for the redox reaction to occur. Hence, the redox reaction is non-spontaneous.
Oxidation: the loss of electron.
Reduction: the gain of electron.
The anode: the electrode where oxidation occurs.
The cathode: the electrode where reduction occurs.
cathode = reduction
anode = oxidation
The most positive potential will be the cathode reaction.
The most negative potential will be the anode reaction.
The reactions are;
