Vedclass · Answer

(A) The Van Arkel method is used for refining metals like $Ti$ and $Zr$. In this process,the crude metal is heated in an evacuated vessel with iodine to form a volatile stable compound. For example: $Ti + 2I_2 \xrightarrow{500 \ K} TiI_4 	ext{ (Volatile stable compound)}$. This volatile compound is then decomposed on a tungsten filament at a higher temperature to obtain the pure metal: $TiI_4 \xrightarrow{1700 \ K} Ti + 2I_2 	ext{ (Pure metal)}$.
