strong acid
Compare with weak acid .A strong acid is an acid that completely dissociates into hydrogen ions and anions in solution. Strong acids are strong electrolytes . There are only six common strong acids: HCl (hydrochloric acid), HBr (hydrobromic acid), HI (hydroiodic acid), H2SO4 (sulfuric acid), HClO4 (perchloric acid), and HNO3 (nitric acid).

Strong acid
A strong acid is an acid that dissociates completely in an aqueous solution (not in the case of sulfuric acid as it is diprotic), or in other terms, with a pKa < −1.74. This generally means that in aqueous solution at standard temperature and pressure, the concentration of hydronium ions is equal to the concentration of strong acid introduced to the solution. While strong acids are generally assumed to be the most corrosive, this is not always true. The carborane superacid (H(CHB11Cl11), which is one million times stronger than sulfuric acid, is entirely non-corrosive, whereas the weak acid hydrofluoric acid (HF) is extremely corrosive and can dissolve, among other things, glass and all metals except iridium. The equation for complete dissociation of an acid in aqueous solution is as follows:
- HA(aq) → H+(aq) + A−(aq)
