Thermodynamics of Ion pair of [MgSO4]0 in i-PrOH Water Mixed Solvent

Abstract

Abstract: The standard second ionization constant of sulphuric acid, K₂ and the standard association constant of ion pair [MgSO₄]⁰, K_D, in_0.05 molar fraction i-PrOH-water mixture at five temperatures, from 278.15 to 318.15 Kwere 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.

Key words: Ion pair, Association constant, EMF, Magnesium sulphate, Sulphuric acid, i-PrOH
