Can u pls explain me briefly abt vapour phase refining?

Answer 1

✌✌HEY MATE!!!

HERE IS YOUR ANSWER

➡ In this method, impure metal is first converted into its volatile compound by heating with a chemical reagent at lower temperature. After this, the volatile compound is decomposed by heating to give the pure metal. e.g., Mond's process for extraction of nickel and Van-Arkel Method for preparing ultra pure titanium are based on the principle of vapour phase refining.
