Electrolytic reduction of alumina to aluminium by Hall - Herault proce – InterviewSolution

1.	Electrolytic reduction of alumina to aluminium by Hall - Herault process is carried out
Answer» in the presence of NaCl in the presence of fluorite in the presence of cryolite which forms a melt with lower MELTING TEMPERATURE in the presence of cryolite which forms a melt with HIGHER melting temperature Solution :lectrolytic REDUCTION of alumina to aluminium is carried out in the presence of cryolite `(Na_(3) AIF_(6))` which decreases the M.pt of `Al_(2)O_(3)`
