Which of the following element is extracted using I2 as the reactant ?

The crude metal is heated in an evacuated vessel with iodine. The metal iodide being more covalent, volatilizes Zr + 2I2 → ZrI4 The metal iodide is decomposed on a tungsten filament, electrically heated to about 1800K. The pure metal is thus deposited on the filament. ZrI4 → Zr + 2I2

Detailed Solution

The crude metal is heated in an evacuated vessel with iodine.
The metal iodide being more covalent, volatilizes
Zr + 2I₂ → ZrI₄
The metal iodide is decomposed on a tungsten filament, electrically heated to about 1800K.
The pure metal is thus deposited on the filament. ZrI₄ → Zr + 2I₂
