Regarding this week’s selected substance:

Fluoroantimonic acid (HSbF6), the strongest known superacid, is made by combining hydrofluoric acid with antimony pentafluoride and can be as much as 2 x 1019 times stronger than 100% sulfuric acid.  However super acids are all as strong as one another in aqueous solution, other solvents need to be used to see their effect. 

Fluoroantimonic acid
