Q. The production of dihydrogen gas via water-gas shift reaction
$ CO(g) + H_{2}O(g) \xrightarrow[\text{Catalyst}]{\Delta} CO_{2}(g) +H_{2}(g) $
The $ CO_{2} $ gas is removed by scrubbing with solution of

AMUAMU 2014Hydrogen

Solution:

The given equation, i.e., water gas shift reaction, is used to increase the production of hydrogen gas. Here, the obtained carbon dioxide $(CO_{2})$ is removed by scrubbing with a solution of sodium arsenite
