Explanation of Solution
In the Hall-Heroult reaction, the smelting of aluminum takes place. In this process, aluminum oxide is dissolved in molten cryolite.
The reactions at the cathode and anode are represented as follows:
Cathode-Reduction reaction:
Anode-Oxidation Reaction:
The overall cell reaction will be:
Here, cryolite has a melting point of approximately
