Explain with chemical equations the industrial production of dihydrogen gas.

Industrial production of dihydrogen gas:

i. In industries, the production of gas is carried out from methane (natural gas).

ii. In this process, methane mixed with water over nickel catalyst to form a mixture of carbon monoxide and dihydrogen gas.

iii. This mixture is called water gas.

iv. By reaction of water gas again with water, excess dihydrogen gas is formed and carbon monoxide is removed.

CO + H₂O → CO₂ + H₂

v. To separate H₂ gas from this mixture, it is passed through water.

vi. This way it can be collected in gas jar.
