Which method of purification is represented by the following equation ?
$Ti(s) + 2I_2(g) \xrightarrow{{523\,K}} $ $Ti{I_4}(g)\xrightarrow{{1700\,K}}Ti(s) + 2{I_2}(g)$
A
Zone refining
B
Cupellation
C
Polling
D
VanArkel
(AIEEE-2012)
Solution
Van Arkel is a method in which heat treatment it used to purify metal in this process metals are converted into other metal compound for loosly coupled like as iodine to make metal iodide which are easily decomposed and give pure metal. The process is known as Van Arkel method.
