The density and molecular complexity of gaseous hydrogen fluoride

Abstract

1. The vapor density of hydrogen fluoride has been determined at a series of temperatures below its boiling point. 2. The data obtained, together with the extensive data of Thorpe and Hambly at higher temperatures, have been closely calculated by assuming that the vapor contains an equilibrium mixture of HF and (HF)6with a heat of association of 6670 cals, per mole of HF. © 1924, American Chemical Society.
