The values of the thermodynamic second dissociation constant, p K 2 , and related thermodynamic quantities of N-(2-hydroxyethyl)piperazine-N′-2-hydroxypropanesulfonic acid (HEPPSO) have already been reported from 5 to 55 °C, including 37 °C, by the emf method. This paper reports the results for the...
