The Electrical Conductivity of Potasium Halides in Methanol at Different Temperatures

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