LINK: The Power of Sulfuric Acid – Cool Science Demo

The Momma of Superacids (thanks to Alex!)

Just read this article on fluoroantimonic acid, Mr. G! The molecular formula of this acid is HSbF6. It is recorded as the world’s strongest superacid. It sits at -25 on the pH scale, making it 20,000,000,000,000,000,000 times stronger than 100% sulfuric acid. This acid literally dissolves glass, so its containers are made out of PTFE, which is the same stuff that frying pans are coated with to resist high heat and used to coat armor piercing bullets so they are stronger and able to break through concrete and armor easier. This acid is literally INSANE! Here is a picture of those fingers I mentioned earlier today.
