The final, high-temperature step of the Van Arkel process involves the thermal decomposition of Tita — Metallurgy and Isolation of Elements Chemistry Question
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?
Answer: 2
💡 Solution & Explanation
The balanced chemical equation for the final decomposition step in the Van Arkel method is: $TiI_4(g) \xrightarrow{1800 K} Ti(s) + 2I_2(g)$. For every 1 mole of pure Titanium deposited on the filament, exactly 2 moles of Iodine gas are liberated.
