Abstract
Using flow microcalorimetry, the ion association reaction M2+(aq)+Fe(CN) 4−6 (aq)=MFe(CN) 2−6 (aq) (M=Ca, Mg) has been studied at 25°C over the ionic strength range 0.02 to 0.08 mol-dm−3. Analyses of the data to obtain ΔHo, the enthalpy change at infinite dilution, are described. The value obtained for ΔHo is sensitive to the kind of functions used to correct for non-ideal behavior.
