Diamagnetic susceptibility of cadmium ion

Abstract

1. The magnetic susceptibility of a number of cadmium salts of inorganic and organic acids have been measured on the modified form of Gouy's balance. 2. The susceptibility of the cadmium ion has been deduced by the statistical method both from salts of inorganic acids and organic acids; the mean value of the ion obtained from the latter type of salts is significantly higher than that obtained from the former type. 3. From the χm-N graphs, the susceptibility values of anions and cadmium ion in combination with these anions have been determined. The values for the susceptibility of cadmium ion have been calculated in two ways: (i) by multiplying the slopes of the straight lines obtained by plotting χm-N graphs, by the number of electrons in the cadmium ion, and (ii) by subtracting the values of the anions (obtained from the intercepts) from the molecular, susceptibilities of cadmium salts. The former values are more correct. The susceptibility of cadmium ion obtained graphically from various salts of inorganic acids is fairly constant but varies in combination with organic anions. 4. Ionic radius of cadmium has been calculated from the average values for the susceptibility of the ion from salts of inorganic and organic acids.
