Some applications of the conductimetric method with preliminary work for a study of the magnetic susceptibility of adsorbed gases

Abstract

Section I of the thesis deals with the determination of the magnetic balance constant and with the preparation and preliminary measurements of a platinum adsorption medium preparatory to a study of the magnetic properties of adsorbed gases. Section II deals with conductimetric measurements. A description of the apparatus and technique used is given. The method was used, in conjunction with analyses carried out at the British Leather Research Association for the investigation of a number of natural tan extracts to which it was believed that foreign substances had been added. The mobility of the pyridinium ion was also determined, and an attempt made to determine the mobility of the ammonium ion. Finally a rapid method for determining the mobilities of acid anions was studied. It was found unsuitable for difficultly soluble acids, but for easily soluble acids good results were obtainable. The method was used to determine the mobility of the lactate ion.
