Abstract

The dissolution and thermochemical properties of potassium styphnate [K₂(TNR)(H₂O)]n and cesium styphnate [Cs₂(TNR)(H₂O)₂]n in water and N,N-dimethylformamide (DMF) at 298.15 K were studied by calorimetry. The processes are endothermic in water, and exothermic in DMF because of the different molecular structure and polarity of the solutes and solvents. Empirical formulas for the solution enthalpies (Δ_solH), relative apparent molar solution enthalpies (F{cyrillic}L_i), relative partial molar enthalpies (L_i), and dilution enthalpies (Δ_dilH_1,2) are deduced by polynomial expressions, and standard solution enthalpies (Δ_solH_m^θ) are also calculated.
