This paper reports the effect of solvation of the species of citrus fruits in water on its conductivity behaviour as a function of concentration. The specific conductance was measured in two fold dilutions for five different observations and the evaluated equivalent conductance data were analysed by Kraus- Bray conductivity models. Limiting molar conductance (conductance at infinite dilution (λm^∞), and dissociation constant (Kc) were evaluated for their solvent composition. The limiting molar conductance’s (λm∞) were found to decrease with addition of co-solvent (Orange, Grape, Lime, Lemon and Tangerine) to water due to increased solvent-solvent interaction. The Kc values decreased with increase in dilution in all the composition of solvent. This computed values have been used to discuss qualitatively, the suitability of citrus fruits with water in conductance measurement.
