NEETChemistryGeneral Principles and Processes of Isolation of Metals
What reaction occurs at the cathode during the electrolysis of the molten mass in the aluminium extraction process?
Options
- AAl3+ (melt) + 3e- → Al(l)
- BC(s) + O2- (melt) → CO(g) + 2e-
- CAl(l) + 2O2- (melt) → Al 2 O 3 (s) + 4e-
- DCO(g) + 2e- → C(s) + O2- (melt)
Correct answer
A. Al3+ (melt) + 3e- → Al(l)
Step-by-step solution
This reaction occurs at the cathode during the electrolysis process for aluminium extraction.
