A way of making HCl gas is to put Chlorine and Hydrogen into a test tube and expose it to UV light.
This reaction is however fast and strong and I would like to store the Hydrochloride from it.
Another way would be to dissolve Chlorine in water, which would make Hydrochloride, but most of it would go in water and make dilute hydrochloric acid. I could however store the HCl fumes from the dilute acid. I do not know about the practicality of this.
What is the best, and exceptionally practical way of making Hydrochloride when the only resources I have are Hydrogen and Chlorine?
