Vedclass · Answer

(D) In the electrothermal process,calcium phosphate $(Ca_3(PO_4)_2)$ is heated with silica $(SiO_2)$ and coke $(C)$.The silica displaces phosphorus pentoxide $(P_2O_5)$ from calcium phosphate.The reaction is: $Ca_3(PO_4)_2 + 3SiO_2 	o 3CaSiO_3 + P_2O_5$.Subsequently,$P_2O_5$ is reduced by coke to form phosphorus $(P_4)$.

In the electrothermal process,the compound displaced by silica from calcium phosphate is
