The temperature and concentration dependence of the propagation velocity of ultrasound and the adiabatic compressibility is investigated for solutions of lithium chloride and magnesium chloride in n-propyl and n-butyl alcohols. As the temperature is increased the ultrasonic velocity in the solutions decreases monotonically, while the adiabatic compressibility increases exponentially. An increase in the salt concentration of the solution causes the ultrasonic velocity to increase and the compressibility to decrease. The solvation numbers are calculated for the investigated solutions.
