The dependence on temperature of the acid dissociation constants in water for a range of carboxylic acids has been fitted to the Gurney equation using a modified Gauss–Newton method. The equation fits the data reasonably well and identifies the dependence on temperature of the electrical and non-electrical contributions to ln K.
