Acid Strengths
"Concentrated" nitric acid is only 70% pure. Obtaining anything stronger
than that becomes costly and the shelf-life declines markedly. Sulphuric acid is commonly available (god knows why given the fact it's used as a weapon nowadays in the black community) from BnQ., plumbers' merchants and such like at concentrations of about 98% and you don't really need anything stronger than that for general use. Hydrochloric acid seems to top-out at only 36% purity and it's tough to obtain any solution of it stronger than that. Do we have any chemistry aces here who can explain the wide disparity in the maximum strengths of these commonly available acids? |

Its just the way it is with those acids and what they are commonly used for. |

Hydrochloric acid. the concentration is governed by the solubility of the gas hydrogen chloride (the irritating gas given off by brick acid) in water - max possible is 36% Sulphuric acid. As with hydrochl;oric acid but the gas involved is sulphur trioxide whic reacts with the water. Theoreticall 100% is available and can be bought from chemical suppliers Malcolm |

I was not endorsing the sides of buses or the Daily mail. I was merely pointing out that the phenomenal aplomb with which the Guardian totally contradicts the evidence IN ITS OWN ARTICLE in order to present a version of the truth that conforms to the bigotry of its readership, and I selected the guardian PRECISELY BECAUSE it was cited as a reference to prove a point, which it itself does not support, although it claims to. That other news outlets of a less left-leaning nature are very little different, except insofar as tabloids, selling into the tits and bums market, they actually don't pretend the high moral ground that the Guardian does, is not the point. The point is that the Guardian is as post truth and propaganda filled as any tabloid. The only difference being the odor of sanctity that its fast perishing corpse tries to emit. -- "It is an established fact to 97% confidence limits that left wing conspirators see right wing conspiracies everywhere" |

Hydrochloric acid seems to top-out at only 36% purity and it's tough to obtain any solution of it stronger than that. Do we have any chemistry aces here who can explain the wide disparity in the maximum strengths of these commonly available acids? This, from way back in the memory banks. It may not be quite correct in detail, but the gist of it is OK: If you take some dilute nitric acid, and try to concentrate it by boiling to drive off the water, the temperature slowly rises as water is driven off until it reaches 121°C and a concentration of 68%, when it forms what is known as a constant boiling mixture* (CBM), in simple terms the nitric acid (HNO3)is boiling off as fast as the water, and the vapour above the liquid has the same composition as the boiling liquid, so the boiling liquid never gets more concentrated. If you want stronger nitric acid, known as fuming nitric acid, you have to distil it from a mixture of sulphuric acid and potassium nitrate, but even then you can only get a maximum of 99%, because the nitric acid itself dissociates into N2O5 and H2O and forms another CBM. 2HNO3 - N2O5 + H2O. Pretty much the same explanation goes for hydrochloric acid, although here the CBM at atmospheric pressure is at 110°C and a concentration of about 20% HCl. But because HCl gas is very soluble in water, if you distil a solution under reduced pressure, the water boils off in preference to the HCl, and you get higher concentrations; lab grade conc. HCl is about 37%, as you say. Whiffy stuff! But H2SO4 doesn't easily evaporate, unlike the two above, and H2SO4 forms a CBM with water of 98% that boils as 330°C, so can't be made any more concentrated by distillation. * https://en.wikipedia.org/wiki/Azeotrope Very good explanation of acid strengths. Just to gild the lily, also see: https://en.wikipedia.org/wiki/Oleum -- Jeff |
