Which of the following chemical reactions represents Hall-Heroult Process?
Updated On: Mar 21, 2025
- \(Cr_2O_3 + 2Al → Al_2O_3 + 2Cr\)
- \(2Al_2O_3 + 3C → 4Al + 3CO_2\)
- \(FeO + CO → Fe + CO_2\)
- \([2Au(CN)_2]-_{aq}+Zn(s)→ 2Au(s) + [Zn(CN_4)]^{2-}\)
Hide Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Hall-Herault process is used for the extraction of aluminium by electrolysis molten \(Al_2O_3\)
\(2Al_2O_3 + 3C → 4Al + 3CO_2\)
