Abstract
A LARGE number of aqueous solutions of electrolytes have been investigated for frequency-, concentration- and temperature-dependence of their absorption of sound in the frequency-range 8 kc./s. to 15 Mc./s. It has been found that all uni-univalent salts investigated have no measurable sound absorption, that is, their excess absorption in concentrations up to 1 mole per litre is less than 10 per cent of the absorption of pure water. This proved to be the case also for a number of bi-univalent salts, except for high concentrations of sodium sulphate and magnesium chloride.
