Abstract

Solubilities of L-glutamic acid, 3-nitrobenzoic acid, p-toluic acid, calcium-L-lactate, calcium gluconate, magnesium-DL-aspartate, and magnesium-L-lactate in water were determined in the temperature range 278 K to 343 K. The apparent molar enthalpies of solution at T = 298.15 K as derived from these solubilities are Δ_solH_m (L-glutamic acid, m_sat = 0.0565 mol·kg⁻¹) = 30.2 kJ·mol⁻¹, Δ_solH_m (3-nitrobenzoic acid, m = 0.0188 mol·kg⁻¹) = 28.1 kJ·mol⁻¹, Δ_solH_m (p-toluic acid, m = 0.00267 mol·kg⁻¹) = 23.9 kJ·mol⁻¹, Δ_solH_m (calcium-L-lactate tetrahydrate, m = 0.2902 mol·kg⁻¹) = 25.8 kJ·mol⁻¹, Δ_solH_m (calcium gluconate, m = 0.0806 mol·kg⁻¹) = 22.1 kJ·mol⁻¹, Δ_solH_m (magnesium-DL-aspartate tetrahydrate, m = 0.1469 mol·kg⁻¹) = 11.5 kJ·mol⁻¹, and Δ_solH_m (magnesium-L-lactate trihydrate, m = 0.3462 mol·kg⁻¹) = 3.81 kJ·mol⁻¹.
