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) → Al2O3(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.
