Question

Give the composition of electrolyte taken in Hall Heroult's process.

Answer 1

Composition of electrolyte taken in Hall Heroult's process:

1. An almost natural Aluminium oxide $\left({\mathrm{Al}}_2{\mathrm{O}}_3\right)$ compound, also known as Alumina is immersed at $950°\mathrm{C}(1,750°\mathrm{F})$in a molten electrolyte.
2. It is composed of Aluminium $\left(\mathrm{Al}\right)$, Sodium $\left(\mathrm{Na}\right)$, and Fluorine $\left(\mathrm{F}\right)$, and is electrolyzed to give aluminium metal at the cathode and oxygen $\left(\mathrm{O}\right)$ gas at the anode in the Hall-Heroult’s process.
