Concentrated hydrochloric acid when kept in open air, sometimes produces a cloud of white fumes. The explanation for it is that
(AIEEE 2003)
  • a)
    concentrated hydrochloric acid emits strongly smelling HCI gas all the time
  • b)
    oxygen in air reacts with the emitted HCI gas to form a cloud of chlorine gas
  • c)
    strong affinity of HCI gas for moisture in air results in forming of droplets of liquid solution which appears like a cloudy smoke
  • d)
    due to strong affinity for water, concentrated hydrochloric acid pulls moisture of air towards itself. This moisture forms droplets of water and hence, the cloud
Correct answer is option 'B'. Can you explain this answer?

Explanation:

Reaction with Oxygen:
- When concentrated hydrochloric acid is exposed to air, the strong-smelling HCl gas it emits reacts with oxygen in the air.
- This reaction forms a cloud of chlorine gas, which appears as white fumes.

Formation of Chlorine Gas:
- The reaction between the emitted HCl gas and oxygen in the air produces chlorine gas, which is visible as a cloud of white fumes.

Chemical Explanation:
- The chemical equation for this reaction is 2HCl(g) + O2(g) -> 2Cl2(g) + 2H2O(g).
- The presence of oxygen in the air facilitates this reaction, leading to the formation of chlorine gas.

Conclusion:
- Therefore, the explanation for the production of white fumes when concentrated hydrochloric acid is kept in open air is the reaction of emitted HCl gas with oxygen to form chlorine gas.
