# Vinegar salt reaction to produce acid; does it matter what type of vinegar I use

I am trying to get get hydrogen chloride gas by using the reaction sodium chloride + vinegar = HCl(g) + sodium acetate, does it matter what type of vinegar I use eg apple cider vinegar, malt vinegar; if it does matter where could i find some pure vinegar at a reasonable price

• No it doesn't matter. The result won't change. – Alchimista Sep 21 '19 at 9:22
• Since the reaction won't work for any type of vinegar, the type won't matter. – matt_black Sep 22 '19 at 15:52

1. $$\ce{HCl}$$ is strong acid, $$\ce{CH3COOH}$$ is weak acid. The reaction is practically completely shifted toward acetic acid and sodium chloride. Especially if acetic acid is diluted.
2. $$\ce{HCl}$$ forms azeotrope with water with the maximal boiling point near 20% $$\ce{HCl}$$. If you heat the mixture, that would boil water and acetic acid with minimal traces of $$\ce{HCl}$$ that would dissolve back in the condensate.
