Hello fellow chemists,
i was wondering if you could share some thoughts and maybe help me with a synthesis i want to try.
As the title indicates,  i want to synthesize HCl form very basic components my idea was to just use acetic acid and Sodium chloride but im not sure if the acetic acid is a strong enough acid to get this reaction going the formula that i came up with is CH₃COOH+NaCl→C₂H₃NaO₂+ HCl of course I would need to further concentrate the acetic acid such as by distillation and then mix in the Sodium Chloride in theory there should be HCl gas That i can pass through water to produce hydrochloric acid.
Well that is in theory but im not sure that this will work therefore  im  asking you maybe more experienced chemists what your thoughts about this synthesis are.
(please excuse my bad spelling im from germany and as might tell english is not my native language)
i sincerely hope that your are able to help  me if you need more information or if you got questions about my thought process please leave a comment so i can respond to you.
greetings and thanks from Berlin

HCl is a strong accident CH3COOH is a weak acid . So the equilibrium is on the left side. If you would use sulfuric acid instead of acetic acid then it will work.

A good resource to get you thinking is WIKI

for instance
https://en.wikipedia.org/wiki/Hydrogen_chloride

Laboratory methods
Small amounts of HCl gas for laboratory use can be generated in an HCl generator by dehydrating hydrochloric acid with either sulfuric acid or anhydrous calcium chloride. Alternatively, HCl can be generated by the reaction of sulfuric acid with sodium chloride:[12]

NaCl + H2SO4 → NaHSO4 + HCl

I find the references at the bottom of many WIKI articles are a good resource for further reading.

Hi! I challenged myself to do the same just a few weeks ago. Not sure if you can call it a basic compound, but I made a solution of NaClO and MnO2. After that, citric acid was addded, and I'm really unsure about this, but the products were Cl2, H2O, HCl, MnCl2 and sodium citrate. Might make a post about this later, because its just my hypothesis.

The days when the mixing of the three reagents led to a new scientific discovery are now gone forever.
But even now, such a mixture does not have to be easy to interpret because the reaction can be affected by the concentration, temperature, speed of reaction of individual reagents, even the way of mixing reagents, etc. Already two reagents can react with each other.
You couldn't make NaClO and MnO2 solution. MnO2 does not dissolve in NaClO solution, so it was a suspension. These compounds react with each other only when hot in a very strongly alkalized solution.
The addition of citric acid will immediately break down the hypochlorite to form HOCl, which decomposes slowly with the release of chlorine. If the hypochlorite concentration is low, you may not even notice it because this is an equilibrium reaction. Citric acid reacts with MnO2 undergoing oxidation to CO2 in a large excess of oxidant. These are just a few examples of what could have happened in this mixture.

I dont agree with you AWK, its still possible to find new chemistry just by mixing 3 components I believe.
