Abstract
Enthalpies are determined calorimetrically for the acid–base reactions of N-methylglycine in aqueous solutions of nitric acid and potassium hydroxide at a temperature of 298.15 K and ionic strengths of 0.25, 0.50, and 0.75 (in the presence of KNO3). Standard thermodynamic characteristics of the acid–base reactions of N-methylglycine are calculated. The effect the concentration of the background electrolyte has on the enthalpy of sarcosine dissociation is considered.
