The magnetic properties of zinc and its compounds

Abstract

The object of this research is an investigation of the magnetic properties of Zinc and its commoner compounds. The magnetic susceptibilities of twenty-eight highly purified zinc compounds have been determined , and from a consideration of the values obtained a mean experimental value of the susceptibility of the Zinc ion has been found, a comparison between the experimental value and the theoretical value, calculated from considerations of atomic structure, has been made. From a consideration of the molecular susceptibilities of the compounds measured, it-was found that there is a probable relationship between magnetic susceptibility and co-ordination number. The susceptibilities of the Zinc halides were found and, from a graph showing the relationship between molar susceptibility and the total number of electrons, it was found that Ikenmeyer's flattening of the curve is without justification. From the susceptibilities of the organic salts measured, the value of the group has been calculated; and also, the effect of substituting a Qhlorine atom for a Hydrogen atom in the side-chain of a fatty acid, has been estimated. The zinc salts of the oxy-acids of Phosphorous were found to behave in an anomalous manner. There was found to be some regularity in these compounds showing that the anomaly is similar throughout the series.
