Question

Noble gases are adsorbed by: (A) anhydrous calcium chloride (B) ferric hydroxide (C) cone. H2SO4 (D) activated coconut charcoal

Tardigrade Admin · Accepted Answer

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 difficultly liquifiable gas).
