STUDIES IN HYDROGEN FLUORIDE

Abstract

Studies were carried out to compare the chemical behavior of HF with that of H2O acting as a base appeared to increase the solubility of FeFsub3. EtCl, pentane, methylene chloride, and liquid Cl did not form solid clathrate compounds with HF when added to freshly distilled HF at dry ice temperatures. The latter 2 compounds formed separate layers which might indicate solid HF addition compounds. Cells made in the Kel-F H-tube with saturated Zn and Pb amalgam electrodes and those prepared with Zn and Cd metal and pure Fe and Pb electrodes coated with their metal fluorides were irreversible. None of the electrodes investigated gave reversible or reproducible potentials. Voltage- current curves indicated that high overvoltages are associated with all the electrode processes. In general, the solubilities of the fluorides of metals in HF were similar to the solubilities of the corresponding hydroxides in H2O and were in the order predicted from the periodic table. Numerous metal fluorides formed solid solvates with HF. When similar compounds were compared, the degree of solvation of the solid phase by HF appeared consistent.
