In the Kroll process for making titanium, titanium oxide mixed with carbon and chlorine is passed through the reactor. Titanium tetrachloride vapors distilled off. They are condensed and reduced to titanium sponge by reaction with magnesium metal in an atmosphere of argon. The reactions are: TiO2 + C + 2Cl2 → TiCl4 + CO2 TiCl4 + 2Mg →Ti + 2MgCl2 (i) Calculate the theoretical weights of chlorine, carbon and magnesium required to produce on ton of titanium, assuming that reaction is complete. (ii) Find the weight of the titanium tetrachloride intermediate.
