Hall Heroult Process The method to obtain aluminium from alumina by the electrochemical method was invented by Charles Hall and Paul H roult Electric current cannot pass through the solid form of alumina and the melting point of alumina is also very high
The oxidation and reduction half reactions of the reaction 2Al s 3Cu 2 aq 2Al 3 aq 3Cu s are Electrolytic reduction of alumina to aluminium by Hall Heroult process is carried out View Solution Click here point up 2 to get an answer to your question writing hand explain whyin the electrolysis of alumina using hall heroults process

The hall heroult process is used for smelting of aluminium In the Hall Heroult process the cathode is made of carbon Also here anode is also made up of carbon Hall s process is used for the extraction of Aluminum from Alumina The reaction involved in the Hall s process is as follows A l 2 O 3 2 H 2 O 2 N a 2 C O 3 2 N a A l O 2 C O 2 2 H 2 O
During the extraction of aluminium by Hall He roult process i Neat labelled diagram of electrolytic cell is as shown ii Over all cell reaction is 2 A l 2 O 3 3 C 4 A l 3 C O 2 In the contacts of Hall Heroult process for the extraction of Al which of the following statement is

In the Hall H roult process alumina A l 2 O 3 is dissolved in molten synthetic cryolite N a 3 A l F 6 to lower its melting point for easier electrolysis Was this answer helpful 4 The electrolysis of alumina by Hall and Heroult s process is carried by using a fused mixture of alumina and cryolite along with minor quantities of aluminum fluoride and fluorspar The addition of cryolite and fluorspar increases the electrical conductivity of alumina and lowers the fusion temperature Thus the option A is correct
