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.
