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.Slovensko kemijsko društvo20062015-07-10 18:43:06Delo ni kategorizirano60363UDK: 544.35:544.6.018:544.623ISSN pri članku: 1318-0207COBISS_ID: 27955461OceCobissID: 14086149sl
