Question

Water gas is a mixture of

• A. (A) CO + H₂
• B. (B) CO₂ + H₂
• C. (C) CO + H₂O
• D. (D) CO₃ + H₂

Answer 1

The correct option is A

(A) CO + H₂

Explanation:

Water-gas:

• Water gas is an equimolar mixture of carbon monoxide and hydrogen
• It is prepared by passing steam over red hot coke.

$\underset{\mathrm{Red}\mathrm{hot}\mathrm{coke}}{\mathrm{C}\left(\mathrm{s}\right)}+\underset{\mathrm{Steam}}{{\mathrm{H}}_2\mathrm{O}\left(\mathrm{g}\right)}\to \underset{\mathrm{Carbon}\mathrm{monoxide}}{\mathrm{CO}\left(\mathrm{g}\right)}+\underset{\mathrm{Hydrogen}}{{\mathrm{H}}_2\left(\mathrm{g}\right)}$

This is the industrial production of hydrogen is known as Bosch's Process.

• It is a highly flammable and poisonous gaseous mixture
• It is used together with producer gas(CO + N₂) for the preparation of fuel gas.

Therefore, the correct option is (A).
