| Abstract: | In this paper, the effects of power ultrasound on physical and chemical properties of some solutions are investigated. It is found that with the application of ultrasonic wave, the viscosity and surface tension of some solutions are temporarily reduced, while the electrical conductivity of some solutions is increased, seemingly permanently. |
