| Abstract: | The electrical conductivity of aqueous cyclamic acid was studied in the concentration range (0.0004<c/mol⋅dm−3<0.14) at temperatures ranging from 278.15 to 303.15 K. Conductivities were measured by a precise method and examined by applying extended conductivity equations taking into account dimerization and incomplete electrolyte dissociation. Limiting molar electrolyte and ionic conductivities, dissociation and dimerization constants, and thermodynamic functions associated with dissociation and dimerization of cyclamic acid are discussed. |
