Which method of purification is represented by the following equation: Ti(s)+2\mathrm{Ti}(\mathrm{s})+2\mathrm{I}2(g)⟶523 KTiI4(g)⟶1700 KTi(s)+2_2(\mathrm{g}) \stackrel{523 \mathrm{~K}}{\longrightarrow} \mathrm{TiI}_4(\mathrm{g}) \stackrel{1700 \mathrm{~K}}{\longrightarrow} \mathrm{Ti}(\mathrm{s})+2\mathrm{I}2(g)_2(\mathrm{g})

Options

  1. Azone refining
  2. Bcupellation
  3. CPoling
  4. DVan Arkel

Correct answer

D. Van Arkel

Step-by-step solution

Van Arkel method Ti(s)+2I2(g)⟶523 KTiI4(g)Til4(g)⟶1700 KTi(s)+2I2(g)\begin{aligned} & \mathrm{Ti}(\mathrm{s})+2 \mathrm{I}_2(\mathrm{g}) \stackrel{523 \mathrm{~K}}{\longrightarrow} \mathrm{TiI}_4(\mathrm{g}) \\ & \mathrm{Til}_4(\mathrm{g}) \stackrel{1700 \mathrm{~K}}{\longrightarrow} \mathrm{Ti}(\mathrm{s})+2 \mathrm{I}_2(\mathrm{g}) \end{aligned}
