Abstract
The problems of determining fluoride in both organic and inorganic materials have long been investigated. Yet near-perfect or universally accepted procedures or methods have not been established and the search continues. Gravimetric procedures have a number of limitations, and volumetric procedures do not seem to offer convenient or sharp end points. Research done in this University has dealt with gravimetric precipitation of lead chloride fluoride, and some of the limitations that accompany the method were successfully eliminated. Relatively recent, a parallel method has been offered employing the bromide ion in place of the chloride ion in forming the precipitate. However, the procedure involved a volumetric finish to the analysis, i.e., the fluoride was precipitated as lead bromide fluoride and the precipitate redissolved and analyzed for bromide ion by means of the Volhard method. The purpose of this work is to investigate the precipitation of lead bromide fluoride as a purely gravimetric method and to compare it with the lead chloride fluoride method.
