Question:-
what is hall's process
AnsWeR:-
the process by which aluminum is produced consisting of electrolysis of a molten solution of purified alumina in cryolite at a temperature of about 950°C.Hall moved on to experiment with cryolite (sodium aluminum fluoride) as a solvent. He made cryolite, found that it would melt in his furnace, and showed that it would dissolve more than 25% by weight of aluminum oxide. The melting point of cryolite is 1000° C, an exceptionally high temperature for electrochemistry.
