What happens if you get Fluoroantimonic acid?

HF/SbF5 is an extremely corrosive and toxic substance that is sensitive to moisture. As with most strong acids, fluoroantimonic acid can react violently with water due to the exothermic hydration. Heating fluoroantimonic acid is dangerous as well, as it decomposes into toxic fluorine gas.

What is a superacid and what is it used for?

Common uses of superacids include providing an environment to create, maintain, and characterize carbocations. Carbocations are intermediates in numerous useful reactions such as those forming plastics and in the production of high-octane gasoline.

Why is Fluorosulfuric acid a superacid?

It has an H0 value of −15.1 compared to −12 for sulfuric acid. The combination of HSO3F and the Lewis acid antimony pentafluoride produces “Magic acid”, which is a far stronger protonating agent. These acids all fall into the category of “superacids”, acids stronger than 100\% sulfuric acid.

What to do if a concentrated acid spills over your hand?

If a few drops of a concentrated acid accidentally spill over the hand of a student, wash the hand immediately with plenty of water and apply a paste of sodium hydrogen carbonate. Water will dilute the acid and wash it out.

What happens if you spill acid on your skin?

If the acid spilled is H2SO4 (Sulphuric acid) or HNO3 (Nitric acid), There’s nothing to worry. Firstly, wash the affected area several times with running tap water. The skin will start to turn yellowish. There’s nothing to be scared about it.

What happens when you put sodium hydrogen carbonate on your hands?

If a few drops of a concentrated acid accidentally spill over the hand of a student, wash the hand immediately with plenty of water and apply a paste of sodium hydrogen carbonate. Water will dilute the acid and wash it out. Any remaining acid will be neutralized with sodium hydrogen carbonate.

What are some examples of superacids?

NECHU already gave an accurate definition of the term Superacid. I’ll just add to this by listing some common examples of superacids: Fluorosulfuric acid (FSO3H, H0 = -15.1). This is one of the strongest single-molecule acids, and is formed by the combination of HF and SO3.
