Abstract In recent years the strengths of many acids have been determined by exact methods and the work of Harned and Embree (1934) on the dissociation constants of acids at different temperatures has given us precise know ledge of the thermodynamic functions associated with the ionization of these substances. No similar measurements had been made with uncharged bases until Pedersen (1937a) determined the dissociation constants of aniline and o-chloraniline, Pedersen (1937b); the accepted values for the common bases are derived from old measurements which can no longer be regarded as sufficiently precise.
