• The calorimetric method was employed to measure the heat effects of the interaction of isonicotinic and picolinic acids with HNO 3 in aqueous solutions over different pH ranges at 298.15 K and ionic strengths of 0.5, 1.0, and 1.5 against potassium nitrate. The heat effects of stepwise dissociation of the acids were determined. The standard thermodynamic characteristics (Δ r H °, Δ r G °, Δ r S °, Δ C p °) of the acid-base reactions in aqueous solutions of isonicotinic and picolinic acids were calculated.
