Effect of the resonance parameter on a chemical reaction subjected to ultrasonic waves

Abstract
Experimental results are presented which indicate that the application of a fixed intensity of ultrasonic waves to a water‐tetrachloride solution containing dissolved air provides yields of chlorine varying from zero to maximum simply as a function of the liquid height in the capillary above the transducer. The difference in heights of the liquid between zero and maximum yields is found to be equal to one‐quarter the wavelength of the ultrasonic wave in the liquid. A mathematical model to explain this phenomenon is presented.
