Question: What's the most acidic chemical currently discovered?

  1. @misseden Chemistry isn’t my field of science, but the neat thing about training as a scientist is that you get taught where to go to find information and how to find answers.

    Acids can be measured by strength and corrosiveness. So the strongest is not necessarily the most corrosive and vice versa.

    So, through the magic of internet searching, I’m going to back:
    Fluroantimonic acid (http://en.wikipedia.org/wiki/Fluoroantimonic_acid) as the strongest known and highly corrosive superacid.

    Or maybe Carborane acid (strong, but not very corrosive) (http://www.nature.com/news/2004/041115/full/news041115-5.html) which was created in a lab – does that count as ‘discovered’?

  2. Agree with Mia, but wanted to add that fluoroantimonic acid is actually an acid (hydrofluoric acid) mixed with another compound (antimony pentafluoride), whereas carborane acid is the strongest acid as a single component. Notice how fluorine (the most electronegative element) is involved with the first acid. Most people would never come across these acids in real life.

  3. You might like to know that hydrofluoric acid is so strong it cannot be kept in a glass container.

  4. Well I’ve just been beaten to the answer by everyone else.
    And everyone else is right of course.

    The only thing I can add is that the acid that @Mia and @DJ a talking about are known as ‘superacids’. Can be very dangerous. Here’s a vid to see why.

  1. ..so where do you store it then?

    • Clever question. Fluoroantimonic acid (or its close relative known as “magic acid”) would be stored in a polymer (plastic) bottle which has fluorine as part of the plastic – similar to the polymer called teflon which is the non-stick coating on frying pans.

  2. No it doesn’t.

  3. Sooo… how is it manufactured?
