The ultrasonic velocity of aqueous solutions of alkali metal chlorides was measured by the use of the singaround technique at 0.5 and 1 mol kg<SUP>−1</SUP> over the temperature range from 30 to 85 °C; compressibilities of the solutions were also determined. It was found that the ultrasound velocity <I>versus</I> temperature curves show a maximum, while the compressibility <I>versus</I> temperature ones show a minimum. Both maxima and minima appear at lower temperatures than that observed for pure water. The maximum shifted values were found for Na<SUP>+</SUP> ion. The results were explained by the dynamic structure of the water around the ions.
