# In context with the industrial preparation of hydrogen from water gas $\dpi{100} (CO+H_2)$, which of the following is the correct statement? Option 1) $CO$ is oxidised to $CO_2$ with steam in the presence of a catalyst followed by absorption of $CO_2$ in alkali Option 2) $CO$ and $H_2$  are fractionally separated using differences in their densities Option 3) $CO$  is removed by absorption in aqueous  $Cu_2Cl_2$ solution Option 4) $H_2$  is removed through occlusion with Pd

As we learnt in

Water Gas Shift Reaction -

Reaction of $CO$ with water at 673 K in presence of catalyst.

- wherein

Option 1)

$CO$ is oxidised to $CO_2$ with steam in the presence of a catalyst followed by absorption of $CO_2$ in alkali

This  option is correct

Option 2)

$CO$ and $H_2$  are fractionally separated using differences in their densities

This  option is incorrect

Option 3)

$CO$  is removed by absorption in aqueous  $Cu_2Cl_2$ solution

This  option is incorrect

Option 4)

$H_2$  is removed through occlusion with Pd

This  option is incorrect
