Abstract EN
The audio electrical conductances of aqueous solutions of magnesium, manganese II, barium, and copper succinates have been measured at various temperatures in the range of 298.15 K to 313.15 K, using an audio frequency conductance bridge.
The evaluation of conductance data was carried out by minimisation technique using the theoretical equations of the complete and modified forms of Pitts (P) and Fuoss-Hsia (F-H), each a three-parameter equation, association constant (KA), molar conductance (Λm), and distance parameter (a).
Quantitative results showed that these salts do not behave as “strong” electrolytes, and that their dissociations are far from complete.
The abnormally low conductances of these electrolytes are not due to the presence of electrically neutral molecules but to the ion-pair formation.
The Walden product values, as well as the standard thermodynamics functions (ΔH∘, ΔG∘, ΔS∘) for the association reaction at the four temperatures studied, have been evaluated.
