Choose the correct statement about the industrial preparation of hydrogen from water gas \[(CO+{{H}_{2}})\],

A)  \[{{H}_{2}}\] is removed through occlusion with Pd

B)  CO and \[{{H}_{2}}\] are fractionally separated using differences in their densities

C)  CO is removed by absorption in aq. \[C{{u}_{2}}C{{l}_{2}}\]solution

D)  CO is oxidised to \[C{{O}_{2}}\] with steam in the presence of a catalyst followed by absorption of \[C{{O}_{2}}\] in alkali

Correct Answer: D

Solution :

CO is first oxidised to \[C{{O}_{2}}\] with steam followed by absorption of \[C{{O}_{2}}\] in alkali
