Influence of Permanent Magnet on the Association Constants of FeCl3+10% PVA (Polyvinylalcohol) in 50% Ethanol-Water Solutions Conductometrically at 298.15K: Using New Equation for 1:3 Asymmetric Electrolytes

The external poles of a permanent magnet of power 1.26 kG were used to study their effect on the conductance values of FeCl3 plus 10% by weight , PVA (polyvinylalcohol) in 50 % by weight mixed ethanol-water solutions. A new equation for 1:3 asymmetric association constant was derived and used for calculating the association constants (KA) for FeCl3 solutions in 50 % ethanol (EtOH)-H2O mixture in presence of PVA and also in 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.
