Hydrochloric Acid from vinegar and salt
« on: April 13, 2006, 07:35:55 AM »

Is it possible to create hydrochloric acid by dissolving salt into vinegar, CH3COOH + NaCl ==> HCl + ''some Sodium compund?''

Lets assume you are using table salt.

NaCl + CH3COOH --> Na(OOCCH3) + HCl

Theoretically, it should be possible.

I highly doubt any appreciable HCl could be made by the above method.

Forget about this. Acetic acid is a weak acid and it certainly won't give up its protons to form a strong acid like HCl. Going the other way around does work. When you add sodium acetate to hydrochloric acid, then you obtain acetic acid and table salt.

Maybe, you could get some HCl in low yield if you add waterfree acetic acid (glacial acetic acid) to table salt. This depends on the solubility of HCl in acetic acid. At low solubility some HCl may be driven off.

Imagine what would happen when you put put vinegar on some salted chips (french fries)! :o

I don't think this would happen at all even if you used anhydrous CH3COOH.
