Talk:Fluorosulfuric acid

Magic acid

The comment "Fluorosulfuric acid is often marketed by suppliers, such as Aldrich, as a antimony pentafluoride solution. This antimony pentafluoride/fluorosulfuric acid mixture is commonly known as magic acid." is erroneous.

Magic acid does contain FSO₃H, and this point is well worth noting, but Magic acid is not a mere marketing ploy, it is a different chemical from FSO3H. Magic acid is a superacid, and I dont think that FSO₃H is. This requires some further reading. Smokefoot 03:38, 6 February 2006 (UTC)[reply]

"Magic acid is a superacid, and I dont think that FSO₃H is." Erm... actually, it is. Just read the article. 86.149.111.11 (talk) 18:08, 25 September 2009 (UTC)[reply]

Footnote Updates Needed

http://en.wikipedia.org/wiki/Wikipedia:Footnotes

The footnotes need to be updated as per the Wiki standard - agree anyone?

Yep the footnotes are strange. A young student did this report for my class, and we are semi-clueless on format nicities. --Smokefoot 00:44, 17 March 2006 (UTC)[reply]

Fluorosulfuric acid eats right through glass?

http://en.wikipedia.org/wiki/Fluorosulfuric_acid says: When freed from HF by sweeping with an inert gas, it can be distilled in glass apparatus [3].

While http://en.wikipedia.org/wiki/Carboranes says: ...such as fluorosulfuric acid that eats right through glass [2].

So which is correct? Is it the HF that eats through glass, which it is known to do?

FSO₃H does not attack glass according to the Encyclopedia for Reagents for Organic Synthesis. FSO₃H hydrolyzes to release HF, which does attack glass. I removed the misleading statement from the article. Also, colorful language like "eat glass" is fun to read but not very informative. Someone should take a look at the carborane article to help rebalance it, because carboranes are bigger than the derived acids being studies recently. --Smokefoot 13:49, 15 April 2006 (UTC)[reply]

During an anorganic praktikum in the late 80ies, I worked with fluorsolfonicacid - the compound was stored in metal flasks made from monel metal but the reacion itself was conducted in glas - thoroughly dried and with teflon seals. ciao Pentaclebreaker (talk) 06:52, 13 July 2023 (UTC)[reply]

Related Compounds

The 'Related Coumpounds' section included antimony pentafluoride, which I did not consider to be a related compound. I removed it and added sulfuric acid, which is if anything the most related compound of all. 86.149.111.11 (talk) 18:05, 25 September 2009 (UTC)[reply]

It should be a "related" compound" as it forms in combination with Fluorsulfuric Acid "Magic Acid". Sulfuric acid has a strong similarity as one of the OH groups of the sulfuric acid is substituted with Fluorine. ciao Pentaclebreaker (talk) 13:01, 13 July 2023 (UTC)[reply]

Safety

The phrase "every drop makes a little explosion" is not well worded. The reaction is violent, but depends heavily on concentration and temperature. I changed it to read more professionally. —Preceding unsigned comment added by Hobobot (talk • contribs) 20:28, 17 February 2010 (UTC)[reply]

References

Please correct the source of the MSDS (Sigma Aldrich) to the correct reference number (1), i am not able to edit the reference list. Graphene15 (talk) —Preceding undated comment added 09:51, 21 April 2019 (UTC)[reply]
