An empirical relation to predict ultrasonic velocity in electrolytic solutions

An empirical relation to predict ultrasonic velocity in an electrolytic solution in terms of the surface tension and density of and ultrasonic velocity in water and surface tension, density and a function f(α) of degree of dissociation of the solution is suggested. The relation may be used to predict ultrasonic velocity at any concentration of the solution, provided the ultrasonic velocities at two other concentrations are known. The agreement between the predicted and observed values is good.
