Answer: 8) With the help of this discription given below draw neat and labelled diagram. In this method electrolysis of molten mixture of alumina (melting point > 2000 °c ) is done in a steel tank. The tank has a graphite lining on the inner side. This lining does the work of a cathode. A set of graphite rods dipped in the molten electrolyte works as anode. Cryolite (Na2A1F2) and fluorspar (CaF,) are added in the mixture to lower its melting point upto 1000 °C. Reply
