MCQ
Purification of aluminium done by electrolytic refining is known as
  • A
    Serpeck's process
  • B
    Hall's process
  • C
    Baeyer's process
  • ✓
    Hoop's process
✓

Answer

Correct option: D.
Hoop's process
d
Purification of aluminium by electrolytic refining is called Hoope's process. By this method $99.9\, \%$ pure aluminium metal is obtained. The cell used in this method consists of three layers. In the cell pure $Al$ acts as cathode while anode is of impure $Al.$
