I expect that my memory was wrong on which was which. Thanks for the verification. I do know, however, that in equal concentrations they are equally chemically reactive (corrosiveness). One is not "more bad" than the other. The concentration of the muriatic acid sold for commercial use will be fairly low, otherwise the EPA, lawyers, & others would be having a field day condemning it, & people would be buggering themselves regularly because of careless handling. I have used HCL at the 36N (very reactive) concentration to pickle (remove oxidation) from gold which has been heated to around 1300 degrees F for casting. FWIW, if you combine HCL with HNO3 (nitric acid) you get a concoction known as Aqua Regia (Royal Water) which will dissolve gold. This has gone a little beyond the subject of how to best store this stuff which, I think, you answered very well. I thought the additional info. might be of some interest.muratic is diluted hydrochloric acid sulfuric is the realy bad acid that is in batteries
Correction: Mad professor gave the best answer to the storage question. You corrected me on the identification of muriatic acid. Thanks to boyh.I expect that my memory was wrong on which was which.

Thanks again for the specifics. It has been 56yrs. since my gen. chem. class in college. The numbers & details mean something to me &, I think, to many others on here. I would expect that you teach chemistry. Judging by the response from NCFarmboy many or most will switch to glass containers.Concentrated hydrochloric acid is 37% HCl, 12.1 molar (12.1N), the common name for the 50% dilution is muriatic acid.
Concentrated Sulfuric acid is 98 % H2SO4, 18 molar (36N), common name is oil of vitriol. Undiluted it is a stronger acid than hydrochloric acid, the reason being the actual acid in concentrated hydrochloric acid is the hydronium ion (i.e. protonated water). Diluted Sulfuric acid is of similar strength as the same normality hydrochloric.
Nitric acid is an oxidizing acid, whose oxidizing power is increased when mixed with stronger acids (HCl, H2SO4), the reason being is production of the nitronium ion , NO2+
Yes , glass with a teflon lined cap is best.
To stop any escape of HCl gas the cap can be dipped in hot (or sealed with wax from a candle) wax/parrafin. Another way to seal the cap is to wrap it with parafilm.
P.S. yes, been teaching chemistry 22 years now.
Where do you get a glass jar with a teflon lined cap?
Find a slow running drain to clean and get rid of it.
I've got a gallon that's maybe 10 years old. The plastic jug is getting brittle. I'm going to have to do something with it (just not sure what.)
Spill a gallon of muriatic acid on a lime stone driveway and watch it fizz! :msp_ohmy:
.
Wax is a material that "breath". Not totally leak proof. I make cheese and wax them fir aging, as it age it release mousture trough the wax. Just my though.You can seal the cap with molten wax. :msp_smile:
