In technical words, the acid which dissociates completely into H+ ions in water will have the lowest pH value, while the base dissociates completely into OH- ions in water will have the highest pH value. EDIT : Strongest acid has pH of 1 while strongest base has pH of 14. (0 - 6.99 are acids. 7 is neutral.
Considering this, which is the strongest acid?
The carborane superacid H(CHB11Cl11), which is thousand times stronger than the strength of sulfuric acid, is entirely non-corrosive, whereas the weak acid hydrofluoric acid (HF) is corrosive and can dissolve, among other things, glass and most metals.
Which is the strongest acid in the world?
The carborane superacids may be considered the world's strongest solo acid, as fluoroantimonic acid is actually a mixture of hydrofluoric acid and antimony pentafluoride.
