Influence of Permanent Magnet on the Association Constants of FeCl3 in 50 % Ethanol−H2O Solutions (Conductometrically) at 298.15 K Using a New Equation for 1:3 Asymmetric Electrolytes

Abstract

The external two poles of a permanent magnet of a power of 1.26 kG were used to study their effect on the conductance values of FeCl3 in a 50 % by weight mixed ethanol−H2O solvent. The results were compared with values in the absence of the magnet. A new equation for the 1:3 asymmetric association was obtained and used for the calculation of the association constants (KA) for FeCl3 solutions in a 50 % ethanol (EtOH)−H2O solvent in the absence and presence of an external magnetic field. The new equation was derived from the Fuoss−Shedlovsky equation and Ostwald dilution law, and the evaluated values are discussed.
