Ultrasound propagation in NH3ndash;H2O mixtures

摘要

Data on the sound velocity and absorption in liquid mixtures of NH3and H2O are presented. The sound velocity at 10 MHz was measured as a function of concentration and temperature. The absorption was measured as a function of frequency (between 10 and 85 MHz), concentration, and temperature. The results indicate that the NH3minus;H2O system behaves ultrasonically like mixtures of associated liquids with a relaxation due to the electrolytic nature of NH3.
