The major role of flourspar, `CaF_(2)` which is added in small amount

1.	The major role of flourspar, `CaF_(2)` which is added in small amount in the electrolytic reduction of `Al_(2)O_(3)` dissolved on fused cryolite in fused cryolite isA. to acts as catalystB. to make the fused mixture very conductingC. to increase the temperature of the meltD. to decrease the rate of oxidation of carbon at the anode.
Answer» Correct Answer - B `CaF_2` Ionic compound ionises to give ions & thus increases the number of ion in the electrolyte and as impurity decreases the melting point of `Al_2O_3`
