Vedclass · Answer

(D) The $Van \ Arkel$ method is used for the refining of $Zr$ and $Ti$. The $Van \ Arkel$ process involves heating the impure metal with iodine to form a volatile complex. This complex,upon decomposition at high temperatures,yields the pure metal. For $Zirconium$: $Zr 	ext{ (impure)} + 2I_2 ightarrow ZrI_4$ $ZrI_4 ightarrow Zr 	ext{ (pure)} + 2I_2 	ext{ (at } 1800 \ K)$ For $Titanium$: $Ti 	ext{ (impure)} + 2I_2 ightarrow TiI_4$ $TiI_4 ightarrow Ti 	ext{ (pure)} + 2I_2 	ext{ (at } 1800 \ K)$
