InterviewSolution

1.	Noble gases are adsorbed byA. Anhydrous calcium chlorideB. ferric hydroxideC. Conc. `H_(2)SO_(4)`D. Activated coconut charcol
Answer» Correct Answer - D Noble gases are adsorbed by coconut charcoal. The adsorption of different noble gases occur at different temperatures, hence charcoal is used to separate these gases. Helium is not adsorbed by charcoal (as it is very difficult liquifiable gas).
