The aqueous solubilities of nitrogen trifluoride and dinitrogen tetrafluoride

Abstract

An apparatus has been designed for the measurement of very low gas solubilities (ca. 10–6 mol fraction), allowing fast equilibration between the solute and solvent. The solubilities of NF3(298–318 K) and of N2F4(288–318 K) in water have been determined, and the enthalpies and entropies of solution derived.
