SUMMARY

Hydrochloric acid can be easily produced from hydrogen chloride by dissolving it in water or utilizing room humidity, resulting in dense white fumes. The discussion raises the question of whether hydrogen chloride can be extracted from hydrochloric acid, highlighting that a method involving concentrated sulfuric acid can dry hydrochloric acid to collect HCl gas. However, this approach is deemed impractical for industrial applications as it essentially reverses the initial process of producing hydrochloric acid.

PREREQUISITES
  • Understanding of chemical reactions involving acids and gases
  • Knowledge of concentrated sulfuric acid properties and applications
  • Familiarity with industrial chemical processes
  • Basic principles of gas solubility in liquids
NEXT STEPS
  • Research methods for gas extraction in chemical processes
  • Learn about the industrial applications of hydrochloric acid
  • Investigate the properties and uses of concentrated sulfuric acid
  • Explore the principles of gas solubility and phase changes
USEFUL FOR

Chemists, chemical engineers, and industrial process developers interested in acid-base reactions and gas extraction techniques.

It is easy to produce hydochloric acid from hydrogen chloride by simply dissolving it into water or even with room humidity, it is sufficiently to form dense white fumes of hydrochloric acid.

But is it possible to produce or extract hydrogen chloride from hydrochloric acid?
(At best, a cheap and efficient method which can be scaled up to industrial scale)

Many thanks and I am not sure if this belong to homework section as this is not a homework...

It will be a really dumb industrial procedure because you prepare the acid by dissolving the gas in water. If you add concentrated sulfuric acid to hydrochloric acid you'll be able to dry it and collect the HCl gas but it doesn't make sanse.
