Strongest acid – Fluoroantimonic acid
Strongest acid – Fluoroantimonic acid – Actually, it is a super acid that is a mixture of hydrofluoric acid (HF) and antimony pentafluoride (SbF5). It is a thousand trillion times stronger than concentrated sulfuric acid. Even short-term contact with the skin can result in serious injuries or death – just like inhaling its vapors. Fluoroantimonic acid is stored in special containers.
