| Abstract: | Enthalpy of mixing for six possible combinations
of solutions of NaCl, KCl, NaBr and KBr have been determined as a function of ionic
strength. The experiments have been performed at constant ionic strengths of 1.0
and 2.0 mol kg-1 at 298.15 K using LKB now microcalorimeter in water
+1,4-dioxane mixed solvent system. Data differ appreciably from
corresponding data in water and even do not
support Young's Cross Square Rule. Pitzer ion-interaction model is utilized to obtain
binary and triplet interaction parameters i.e. Θ N
and ΨNX .The data suggest that deviation from Young Cross
Square Rule may arise from preferential solvation of the ions and ion clusters,
as organic cosolvent is also incorporated in
the solvation shell.
