Which method of purification is represented by the following equations
`Ti +2I_(2) overset(523K)rarr TiI_(4) overset(1700K)rarr Ti +2I_(2)`

A

Cupellation

B

Poling

C

Electrolytic refining

D

Van-Arkel process

Text Solution

Verified by Experts

The correct Answer is:
D
This scheme take place in Van Arkel process. By this process ultrapure metal is prepared, the impure metal is first converted into a volatile stable compound generally iodide leaving behind the impurities which is then decomposed at a higher temperature to give the pure metal. Metal like titanium, zirconium are purified by this method.
