Question

do a research work on the electolytic refining of aluminium and write the observation and balanced chemical equation for the reaction

Answer 1

Explanation:

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.
