在i—PrOH—H2O混合溶剂中硫酸镁离子对缔合热力学研究

The standard second ionization constant of sulphuric acid, K2 and the standard association constant of ion pair ［MgSO4］0, KD, in 0.05 molar fraction i-PrOH-water mixture at five temperatures, from 278.15 to 318.15 K were determined from precise emf measurements of different cells without liquid junction. The results have been discussed in term of the solute-solvent interaction and have been compared with those results in water.
