Acid strength
Measure of the tendency of an acid to dissociate
Acid strength
Acid strength is the tendency of an acid, symbolised by the chemical formula HA, to dissociate into a proton, H+, and an anion, A−. The dissociation or ionization of a strong acid in solution is effectively complete, except in its most concentrated solutions. HA → H+ + A− Examples of strong acids are hydrochloric acid (HCl), perchloric acid (HClO4), nitric acid (HNO3) and sulfuric acid (H2SO4). A weak acid is only partially dissociated, or is partly ionized in water with both the undissociated acid and its dissociation products being present, in solution, in equilibrium with each other. HA ⇌ H+ + A− Acetic acid (CH3COOH) is an example of a weak acid. The strength of a weak acid is quantified by its acid dissociation constant, K a {\displaystyle K_{a}} value. The strength of a weak organic acid may depend on substituent effects. The strength of an inorganic acid is dependent on the oxidation...
