Question

Vapour phase refining is used for the purification of Ti because (A) impurities are more soluble in the molten state than in the solid state of the metal (B) low melting Ti can be made to flow on a sloping surface (C) of formation of volatile TiI4 which decomposes to extra pure Ti on heating at high temperature (D) none of these

Tardigrade Admin · Accepted Answer

Correct answer is (c) of formation of volatile TiI4 which decomposes to extra pure Ti on heating at high temperature

Q. Vapour phase refining is used for the purification of Ti because

impurities are more soluble in the molten state than in the solid state of the metal

low melting $T i$ can be made to flow on a sloping surface

of formation of volatile $T i I_{4}$ which decomposes to extra pure Ti on heating at high temperature

none of these

Correct answer is (c) of formation of volatile $T i I_{4}$ which decomposes to extra pure Ti on heating at high temperature
