Vedclass · Answer

(B) To separate the mixture of $SO_2$,$CO_2$,and $O_2$ gases,we need to use reagents that selectively absorb each gas.$1$. First,pass the mixture through acidified potassium dichromate $(K_2Cr_2O_7/H^+)$. This reagent acts as an oxidizing agent and selectively absorbs $SO_2$ gas via a redox reaction.$2$. Next,pass the remaining mixture ($CO_2$ and $O_2$) through limewater $(Ca(OH)_2)$. Limewater is a basic solution that reacts with the acidic gas $CO_2$ to form calcium carbonate,thereby absorbing $CO_2$.$3$. Finally,the remaining $O_2$ gas can be absorbed by alkaline pyrogallol.Thus,the correct sequence is $(II)$,$(I)$,$(III)$.

In a closed container,there is a mixture of $SO_2$,$CO_2$,and $O_2$ gases. Which sequence of reagents can be helpful to separate them?
$(I)$ Limewater
$(II)$ Acidified potassium dichromate
$(III)$ Alkaline pyrogallol
