1. Acid strength

   Acid strength is the tendency of an acid, symbolised by the chemical formula HA {\displaystyle {\ce {HA}}} , to dissociate into a proton, H + {\displaystyle {\ce {H+}}} , and an anion, A − {\displaystyle {\ce {A-}}} . The dissociation of a strong acid in solution is effectively complete, except in its most concentrated solutions. HA ⟶ H + + A − {\displaystyle {\ce {HA -> H+ + A-}}} Examples of strong acids are hydrochloric acid ( HCl ) {\displaystyle {\ce {(HCl)}}} , perchloric acid ( HClO 4 ) {\displaystyle {\ce {(HClO4)}}} , nitric acid ( HNO 3 ) {\displaystyle {\ce {(HNO3)}}} and sulfuric acid ( H 2 SO 4 ) {\displaystyle {\ce {(H2SO4)}}} . A weak acid is only partially dissociated, with both the undissociated acid and its dissociation products being present, in solution, in equilibrium with each other. HA ↽ − − ⇀ H + + A − {\displaystyle {\ce {HA <=> H+ + A-}}} Acetic acid ( CH 3 COOH {\displaystyle {\ce {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_{{\ce {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 state for the atom to which the proton may be attached. Acid strength is solvent-dependent. For example, hydrogen chloride is a strong acid in aqueous solution, but is a weak acid when dissolved in glacial acetic acid.

1. Acid strength

   The strength of an acid refers to its ability or tendency to lose a proton. A strong acid is one that completely ionizes in a solution. In water, one mole of a strong acid HA dissolves yielding one mole of H⁺ and one mole of the conjugate base, A−. Essentially, none of the non-ionized acid HA remains. Examples of strong acids are hydrochloric acid, hydroiodic acid, hydrobromic acid, perchloric acid, nitric acid and sulfuric acid. In aqueous solution, each of these essentially ionizes 100%. In contrast, a weak acid only partially dissociates. Examples in water include carbonic acid and acetic acid. At equilibrium, both the acid and the conjugate base are present in solution. Stronger acids have a larger acid dissociation constant and a smaller logarithmic constant than weaker acids. The stronger an acid is, the more easily it loses a proton, H⁺. Two key factors that contribute to the ease of deprotonation are the polarity of the H—A bond and the size of atom A, which determines the strength of the H—A bond. Acid strengths also depend on the stability of the conjugate base.
