In the literature there are several methods used to obtain solubility information for metal ions in non-aqueous media. However, there is not a well defined method that is accurate or reproducible enough to obtain reliable solubility data. This fact can be illustrated by the inconsistancy of the solubility data reported in the literature for the alkali fluorides. This thesis contains three chapters addressing the determination of metal salts in non-aqueous solvents. In Chapter 1, after a review of existing methods, experiments related to the development of several analysis protocols are described. These protocols are evaluated by determining the solubility of alkali metal fluorides in acetonitrile. Results are used to conclude the merit of each protocol and which protocol is suitable for particular classes of solvents. The second chapter contains experimental details and results of solubility determinations for lithium, sodium, potassium, rubidium, and cesium fluoride in acetonitrile, N,N-dimethylformamide, acetone, benzene, and cyclohexane with and without crown ethers. Some interpretation of the results are included. In the final chapter, a method for determining crown ether solubility in organic solvents by nuclear magnetic resonance is presented and results for several solvents are given.
