Magnetic Studies of Feebly Paramagnetic Ions in State of Solution

Abstract

The magnetic susceptibility of Ammonium dichromate, Sodium dichromate, Potassium chromate and Potassium Permanganate in state of solution has been determined with the help of a very sensitive and accurate microbalance. The values so obtained have been compared with the calculated ones in accordance the additive law. The deviation between the observed and calculated values has been attributed to the effect of the electric field due to distant atoms on the paramagnetic ion and the change of the ionic radii. The change in the moment values in state of solution indicates that in acqueous solution, hydrogen ion concentration is a highly disturbing source. The higher moment values in state of solution than in crystalline state predict the absence of the long range field and thus a release of a part of quenched magnetic moment is resulted.
