Question
Answer the following questions with respect to the electrolytic process in the extraction of aluminum:
Identify the components of the electrolyte other than pure alumina and the role played by each
Solution
Components of electrolyte: Cryolite and fluorspar
Role played by each electrolyte is given below:
- Cryolite lowers the fusion temperature from 2050°C to 950°C and enhances conductivity
- Fluorspar and cryolite act as a solvent for the electrolytic mixture and increase conductivity.
