Chydrohloric acid-increase the concentration

[wolverint]

I read here about evaporation of water from hydrochloric acid to increase the concentration.
Can I do it in a pot on the stove or do I need special equipment?
To what temperature can I heat?
Thanks for help!

You read here about it? Who wrote it? Muriatic acid, like many strong acids and bases, is hydrogen chloride gas suspended in solution (water for example). Can you evaporate it? Fuck, maybe, I've seen some unbelievable shit in my time. I'm just some junky with 22/7 AI chatbots, but if someone bet me money on it, I would drip it in sulfuric acid and bubble it threw new water to a higher concantration. That would probably work. Evaporating the water out? I'd rather waste my money on something more degenerate than fucking up some brick cleaner. Not to say you couldn't do it. I couldn't do it. I couldn't dunk it with 2 hands behind my back either, but I could when I graduated H.S.

It can be concentrated by evaporation of some water up to ~20% HCl (azeotropic mixture: 20.2% HCl with b.p. 108.6 °C at 760 mmHg).
You need at least long Vigreux column to lose less HCl with first fraction.
Distill off water until you get stable ~107-109 C (exact value is depending on your atmospheric pressure) at your still head thermometer.
Then you can cool it down and save your residual 20% hydrochloric acid as is, or purify if by distillation with the same setup, just collecting it as second fraction, if it was initially some yellow technical grade.
To get even more concentrated acid, you need gassing it with HCl gas (for example from another batch of 20% HCl + conc. 80%+ H2SO4).
