Question

The final, high-temperature step of the Van Arkel process involves the thermal decomposition of Titanium tetraiodide ($TiI_4$) gas on a glowing tungsten filament. According to the balanced chemical equation, if exactly $1$ mole of pure solid Titanium is deposited, how many moles of $I_2$ gas are liberated to be recycled?

Prashant Kotian · Accepted Answer

Correct answer: 2. The balanced chemical equation for the final decomposition step in the Van Arkel method is: . For every 1 mole of pure Titanium deposited on the filament, exactly 2 moles of Iodine gas are liberated.
