Fluorine has been obtained by the electrolysis of caesium acid fluoride using a Mathers cell constructed of magnesium. The caesium acid fluoride has a lower melting point and can be more easily regenerated than the usual potassium acid fluoride electrolyte.INTRODUCTION.
SODIUM ARSENITE-SODIUM TELLURATE 3331 observed. These apparently depend upon the nature of the negative ions present in solution.Resistance measurements made by a. c. methods on glass electrodes indicate that most of the apparent resistance obtained by d. c. measurements must be due to polarization.Large increases of apparent resistance of the electrodes result from drying processes even at room temperature, indicating the importance of water, or its ions, in conduction through the glass membranes.Theories designed to explain the operation of glass electrodes are considered in the light of these new experimental results.New York, N.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
