Find out the correlations: Cryolite : Na_3AlF_6 : : Fluorspar :______
State whether the following statements are true or false, correct the false statements. Cryolite (Na_3AlF_6) and Fluorspar (CaF_2) are used to increase the melting point of alumina.
Answer the following questions: In the extraction of aluminium: Write the function and formula of cryolite in the extraction of aluminium .
Give scientific reasons: During electrolytic reduction of alumina, cryolite (Na_3AlF_6) and fluorspar (CaF_2) are added to the electrolytic mixture containing pure alumina
The adjacent figure represents electrolytic reduction of alumina. What is the function of cryolite and fluorspar in this process ?
