Which method of parification is represented by the following equation ?
`Ti(s) + 2I_*(2)(g) rarr TiI_(4)(g) rarr Ti(s) + 2I_(2)(g)`

Options

A. van arkel
B. poling
C. Cupellation
D. zone reflation

Answer

a

Explanation

Van arkel method is very useful for removing all the oxegen nitrogen present in the form imparity in cartain matals like `Zr and Ti`
The process of capellation involves the septration of `Ag` At and after noble metals is placed in a capel, it flat dish made of porous refracting meterail, and a blast of but air is directed upon it in a special furnace , the impurities are oxidried by the air and are partly swept awAy by the blass and partly abserhed by the cupel.
