【 摘 要 】

Three systems, isobutyric acid – water (I–W), “(I-W) + 5 10^-4 M (KCl)” and “(I-W) + 5 10^-3 M (KCl)”, have been studied by measuring the electrical conductivity σ (Ω^‑1cm^‑1) along the coexistence curve in a single phase, as a function of the variations temperature T and composition X in acid. The coefficient σ is a temperature dependent parameter for ions, increasing as temperature is elevated. Contrary to the visconty, the electrical conductivity does not show any anomaly in the critical region.
