How would you prepare HCL acid from hydrogen chloride gas?

Answer 1

Hydrochloric Acid (HCl) is merely Hydrogen Chloride (also HCl) Gas dissolved in pure Water.

To prepare the Acid, very slowly bubble the Gas into a heavy glass flask of Distilled Water no more than about ¼ fill.

CAUTION: This MUST be done in a fume hood with good airflow, and you MUST wear a protective face shield, respirator, protective apron and long gloves.Both the fumes and the liquid are, in a word, Nasty!Your Acid may have a slight yellowish color (depending on the quality of the gas used) due Iron contamination.

The Acid may be purified by distillation. Before you attempt that process, check the literature. There is a mountain of stuff written about this process.

Answer 2

HCl gas can be dissolved in water to prepare hydrochloric acid. This process involves bubbling the HCl gas into a container of water until the desired concentration of hydrochloric acid is achieved. It is important to handle HCl gas with caution, as it is a strong acid and can be harmful if not handled properly.
