| 4. Purification of Hg | D. Chromatography |
Answer & explanation
Correct answer: option 4
Colored bands are observed in chromatography.
Impure metal is converted to a volatile complex by using Mond's process.
Ge and Si are purified by the zone-refining method.
Purification of mercury is done by fractional distillation.
