Van-Arkel method of refining Zirconium involves,
- A removing all oxygen and nitrogen impurities,
- B removing CO impurity
- C removing Hydrogen impurity
- D removing silica impurity
Answer & Solution
Correct Answer
(A) removing all oxygen and nitrogen impurities,
Step-by-step Solution
Detailed explanation
van Arkel method is useful for removing all the oxygen and nitrogen present in the form of impurity in certain metals such
as zirconium and titanium for getting ultra-pure metals. In this method the metal is converted to a volatile unstable
compound taking care that the impurities are not affected during compound formation. The compound thus obtained is
decomposed to get the pure metal.
