an acid that completely dissociates to produce an H+ ion and the conjugate base
An acid that, for practical purposes, ionizes completely under the conditions of interest. Common strong acids are hydrochloric, nitric, and sulfuric. See weak acid.
a compound that ionizes completely in solution to form hydrogen ions and a base
an acidic compound which ionizes completely in an aqueous solution
an acidic compound which ionizes completely or almost completely in aqueous solution
an acid that releases all of its hydrogen ions in solution
an acid which is stronger than the hydronium ion
an acid that ionizes essentially 100% in water. Hydrochloric acid, HCl, is a strong acid. The equation for its ionization in water is HCl(aq) + H2O(l) - H3O+(aq) + Cl-(aq)
An acid that is fully dissociated in solution
an acid that completely dissociates (ionizes) to produce H1 ion and the conjugate base.
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).
A strong acid is an acid that dissociates completely in an aqueous solution, or in other terms, with a pKa < −1.74, that of hydronium. 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.
