r1dermon Posted September 30, 2004 Share Posted September 30, 2004 what would happen if i dumped some cesium hydroxide into hydroflouric acid? one of the strongest bases vs. one of the strongest acids... Link to comment Share on other sites More sharing options...
budullewraagh Posted September 30, 2004 Share Posted September 30, 2004 actually, hydrofluoric acid isn't so strong of an acid. if you reacted the two, you'd end up with cesium fluoride and water vapor mostly. the reaction is quite vigorous Link to comment Share on other sites More sharing options...
fermions Posted September 30, 2004 Share Posted September 30, 2004 I think there are some superacids that doesn't seem to contain H ions but is thousands times stronger than concentrated sulphuric acid... wonder how it works... Link to comment Share on other sites More sharing options...
Gilded Posted September 30, 2004 Share Posted September 30, 2004 I don't know what's the case with HF:SbF5. 50% solution is 10^18 (yes, billion billion) times stronger than super concentrated sulfuric acid. Link to comment Share on other sites More sharing options...
pulkit Posted September 30, 2004 Share Posted September 30, 2004 It depends totally on which concept of acid-base do you use. The H and OH ion is the Arrhenius concept of acid and bases. You also have the Bronstead concept. But the most general one is the Lewis concept. It can explain how chemicals with no H such as SbF5 and AlCl3 are acidic in nature.

r1dermon Posted October 1, 2004 Author Share Posted October 1, 2004 well, how low is hydroflouric on the Ph scale? i saw it on http://www.power-labs.com, it ate through a glass vile in under a minute, and would tear your hand off pretty fast.

YT2095 Posted October 1, 2004 Share Posted October 1, 2004 I`m not sure I totaly agree with ALL of Lewis`s work, he did alot based around ammonia, he seemed somewhat fixated on that chem a bit like Pauling in his later years fixated on Vitamins, some of which has since been dissproven to be false (esp the Vit A trials). however, back to the topic, HF(aq) is not only dangerous in respect of it`s corrosive properties towards flesh, it also acts as an anaesthetic, so you don`t actualy even feel it burn you!

r1dermon Posted October 1, 2004 Author Share Posted October 1, 2004 yeah YT, i've seen the reaction and how much vapor it produces(HF vs. glass) its definately no joke, as one wiff is certain death. in fact, there was so much vapor, that even next to a window, it filled the room and the proceedure had to be evacuated before it found its way through the double filtered gas mask that was being used. i'd say it aint no joke.

pulkit Posted October 1, 2004 Share Posted October 1, 2004 well, how low is hydroflouric on the Ph scale? i saw it on www.power-labs.com[/url'], it ate through a glass vile in under a minute, and would tear your hand off pretty fast. pH is good for comparison, under a particular concentration. You should look at degree of dissociation, which for HF is quite low. It might dissolve glass but it is a weak acid. Weaker than HCl and much much weaker than HI.

jdurg Posted October 1, 2004 Share Posted October 1, 2004 Yeah, HF is pretty weak because the Fluoride ion really likes to hold on to the Hydrogen atom, therefore it does not like to dissociate into H+ and F-. I think hydrofluoric acid kind of proves how arbitrary the "strong"/"weak" designations are when describing acids. (I.E. HF is weak, but I'd rather spill a strong acid such as HCl on my hand than HF). Link to comment Share on other sites More sharing options...
r1dermon Posted October 1, 2004 Author Share Posted October 1, 2004 well, the HF molecule is a lot smaller, allowing it to sink into your skin pores a lot quicker and circ through the blood stream. there have been many fatalities as a result of improper use of HF acid.

budullewraagh Posted October 1, 2004 Share Posted October 1, 2004 and because the fluoride anion will replace most other anions in salts that have relatively active cations Link to comment Share on other sites More sharing options...
akcapr Posted May 22, 2005 Share Posted May 22, 2005 is HF acid more corrosive than acids like HCL and H2SO4? Link to comment Share on other sites More sharing options...
budullewraagh Posted May 22, 2005 Share Posted May 22, 2005 incredibly more so, at equal concentrations, only because of the insanity that is fluorine Link to comment Share on other sites More sharing options...
