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
`underset("Impure")(Ti)+2I_(2) overset(250^(@)C)to TiI_(4) overset(1400^(@)C)to underset("Pure")(ti)+2I_(2)`
This scheme of purification is represented by van-Arkel process.
