STUDIES ON ION-SOLVENT INTERACTIONS OF ELECTROLYTE SOLUTIONS PART 4:OSMOTIC COEFFIENTS OF 2-2 ELECTROLYTES (SULPHATES OF TRANSITION METALS)

摘要

This paper presents the application of the our evaluated dielectric data to the calculations of Osmotic coefficient ,and related parameters of the Bromley ,Pitzers equations for aqueous 2-2 electrolytes namely Copper sulphate,Nickel sulphate,Manganese sulphate and Cobalt sulphate .Several details about the ion pairs, their characteristics , the experimental techniques so far in use for their study, and so far reported important findings are given. Our Results are represented as plots between square root of molality, vc as abscissa and Osmotic coefficients as ordinates in set 1; and between molality, c as abscissa and Osmotic coefficient as ordinates in set 2. The study of the slopes of the graphs reveals several details about the latent Eigen and Tamms Ion-pair formation mechanism .Systematic analysis along with supporting findings from the literature are cited.
