In the correct of the Hall-Heroult process for the extraction of `Al`,

1.	In the correct of the Hall-Heroult process for the extraction of `Al`, which of the following statements is false ?A. `COandCO_(2)` are produced in this proessB. `Al_(2)O_(3)` is mixture and bring conductivityC. `Al^(3+)` is reduced at the cothode to from alD. `Na_(3)AlF_(6)` serves as the electrolyte
Answer» Correct Answer - D `Al_(2)O_(3)` is the electrolyte, which is undergoin the redox process, So, `Al_(2)O_(3)` serves as electrolyte and `Na_(3)AlF_(6)`, although an electrolyte, serves as solvent. Rest all are true.
