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)

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

Footnote Updates Needed[edit]

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)

Fluorosulfuric acid eats right through glass?[edit] says: When freed from HF by sweeping with an inert gas, it can be distilled in glass apparatus [3].

While 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)

Related Compounds[edit]

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. (talk) 18:05, 25 September 2009 (UTC)


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 (talkcontribs) 20:28, 17 February 2010 (UTC)
