| Abstract | ||
| In the present study we have measured the electrical conductivity of some potassium halides (KCl, KBr and KI) in methanol at different temperatures (298-318°K). The conductivity parameters (R, Ka and Λ°) have been calculated by using Lee-Wheaton equation. The thermodynamic parameters (ΔH, ΔG and ΔS) are also calculated for these salts. For the three electrolytes, and at any temperature, it is found that both Λo and Ka increase with increasing temperature following the order: Λo KCl > Λo KBr > Λo KI While KaKCl < KaKBr < KaKI The overall distance parameter (R) is inversely proportional with temperature. | ||
