Summary

The diamagnetic susceptibilities of a few halides of zinc, cadmium and mercury have been studied in the state of solid and in solutions of water and methyl alcohol. Solutions of mercuric chloride in methyl alcohol do not show any departure from the additive law while in all the other cases, an increase in susceptibility is obtained in solutions. The increase is largest in the case of iodides and least in the case of chlorides. The order of change is the same in water and methyl alcohol. The results find an explanation from the conclusions of Fajans relating to inter-ionic deformations. The increase in susceptibility in solution is attributed to the release of deformation of the ions of the molecule by the action of the solvent to the extent of ionisation. These considerations find support from the data on electrical conductivity and the Raman effect.
