| 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 areΔsolHm (l -glutamic acid,msat = 0.0565 mol · kg ? 1) = 30.2 kJ · mol ? 1,ΔsolHm (3-nitrobenzoic acid, m = 0.0188 mol · kg ? 1) = 28.1 kJ · mol ? 1, ΔsolHm( p - toluic acid, m = 0.00267 mol · kg ? 1) = 23.9 kJ · mol ? 1,ΔsolHm (calcium- l -lactate tetrahydrate,m = 0.2902 mol · kg ? 1) = 25.8 kJ · mol ? 1,ΔsolHm (calcium gluconate, m = 0.0806 mol · kg ? 1) = 22.1 kJ · mol ? 1, ΔsolHm(magnesium-dl -aspartate tetrahydrate, m = 0.1469 mol · kg ? 1) = 11.5 kJ · mol ? 1, andΔsolHm (magnesium- l -lactate trihydrate,m = 0.3462 mol · kg ? 1) = 3.81 kJ · mol ? 1. |
