Abstract
A negatively-charged cobalt ferrocyanide sol has been prepared ultrasonically subjecting the washed precipitate of cobalt ferrocyanide and distilled water to ultrasonic waves. The amount of dispersion increases with the time of exposure. The sol is rendered more stable in an ultrasonic field in the presence as well as in the absence of oxygen. The enhanced stability has been attributed to the increase in hydroxyl ions in the medium as a result of the hydrolysis of cobalt ferrocyanide sol. The stability, pH and specific conductivity values are very little affected in the presence of methanol, ethanol and acetone. The inhibition is due to the suppression of cavitation and to a lesser energy release on the collapse of cavitational bubbles.
