Abstract
The electrical conductances of aqueous solutions of zinc, nickel and cobalt succinates have been measured at four temperatures in the temperature range from 298.15K to 313.15K. The limiting molar conductances (Λo), association constants (KA) and the closest distances of approach (a) were calculated using the complete and modified forms of Fouss-Hsia (F/H) and Pitts (P). Quantitative results showed that these salts do not behave as "strong" electrolytes, and that their dissociations are far from complete. The abnormally law conductances of these electrolytes are due to the ion pair formation. The Walden product values, as well as the standard thermodynamic functions (DHo, DGo, DSo) for association reactions have been evaluated.
