Question

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

• A. sodium arsenite
• B. calcium oxide
• C. sodium phosphite
• D. aluminium oxide

Answer 1

Answer: (A)

sodium arsenite

Answer 2

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
