- A Poling
- B zone refining
- C liquation
- D van Arkel's method
Answer & Solution
Correct Answer
(B) zone refining
Step-by-step Solution
Detailed explanation
Poling method This is a method employed in the purification of metal, which contains its metal oxide as an impurity. Copper and tin can be purified by this way, which contains copper oxides and tin oxides as impurities.Zone refining method The principle of zone refining is that…
