In the purification of zirconium by Van Arkel process which halogen is used?

  • A. Flourine
  • B. Chlorine
  • C. Bromine
  • D. lodine

Step-by-step solution

The Van Arkel process (crystal bar process) is used to purify metals like zirconium and titanium. It involves forming a volatile iodide (e.g., ZrI4) which then decomposes on a hot filament to deposit pure metal. Therefore, iodine is the halogen used.
