The thermodynamic dissociation constants of oxalic acid in water and methanol-water mixtures (1938)
AuthorsNicholson, A. J. C.show all
In classical theory of acid-base dissociation acids and bases were characterised by their ability to split off hydrogen ions and hydroxye ions respectively. This definition does not explain the complementary but opposite properties of acids and bases, nor account for their behaviour in non-aqueous media. A more satisfactory definition is that suggested in 1923 by Bronsted and Lowry independently, in the scheme:- [equation here] according to which an acid is a substance which can donate a proton, thus forming a base, while conversely, a base can accept a proton to form an acid.
