Abstract
The electric conductivities of aqueous solutions of rubidium and cesium salts of cyclohexylsulfamic acid, potassium acesulfame and sodium saccharin were measured from 5 °C to 35 °C (in steps of 5 °C) in the concentration range 0.0003 < c/mol dm-3 < 0.01. Data analysis based on the chemical model of electroyte solutions yielded the limiting molar conductivity .. and the association constant KA. Using the known data of the limiting conductivities of rubidium, cesium, sodium and potassium ions the limiting conductivities of the cyclohexylsulfamate, accesulfame and saccharin ions were evaluated. Total dissociation of the investigated salts in water and negligible hydration of anions are evident.

Abstract:
Izmerili smo električno prevodnost razredčenih vodnih raztopin rubidijevega in cezijevega cikloheksilsulfamata, natrijevega saharina in kalijevega acesulfama v temperaturenem obmoèju med 5 in 35 °C v obmoèju koncentracij med 0.0003 . c/ mol dm-3 . 0.01. Na osnovi kemijskega modela smo določili vrednosti molskih prevodnosti pri neskončnem razredèenju, .., ter konstane asociacije ionov, KA, v posameznem sistemu. S pomočjo znanih vrednosti limitnih prevodnosti kationov smo ocenili limitne prevodnosti cikloheksilsulfamatnega, saharinovega in acesulfamovega aniona. Ugotovili smo, da je delež ionskih parov v raztopini zanemarljiv in preiskovanim elektrolitom v vodnih raztopinah lahko pripišemo popolno disociacijo v celotnem obravnavanem temperaturnem območju ter zanemarljivo hidratacijo anionov.
