Conductance studies of sodium salts of some aliphatic carboxylic acids in water at different temperatures
MetadataShow full item record
In this paper the electric conductivities of aqueous solutions of sodium salts of aliphatic carboxylic acids of theH(CH2)nCOOH [n = 0 to 9] types were measured from T/K = (283.15 to 313.15) in the concentration range0.0005bc/mol∙dm−3b0.0200. In terms of the limiting molar conductance (Λο) the measured conductanceresults have been analyzed by the Fuoss–Justice conductance-concentration equation. From these data thecarboxylic ionic contributions (λH(CH2)nCOO−o) to the limiting molar conductance have been estimated. In thispaper the Eyring's enthalpies of activation of charge transportΔH⁎were also calculated. The variations ofλH(CH2)nCOO−oandΔH⁎as the function of the aliphatic chain length of analyzed carboxylic acids were determined.
