Abstract

In the present work the acoustical properties of aqueous solutions of nitrates and chlorides of scandium, yttrium and lanthanum have been investigated by ultrasound velocity measurements. Ultrasound velocity defines the totality of ion-solvent interaction and the peculiarity of the electronic. Dependence of ultrasound velocity on electronic configuration, when the anion is common at 200C was investigated. In the present work was explained why in the nitrate solutions of Y3+ the ultrasound velocity is higher as compared with solutions of Sc3+ and Y3+. Concentration dependencies of ultrasound velocity for chloride and nitrate are presented, as the cation is the same. It was found that this dependence for chloride is linear, but for nitrate it is fitted to a polynomial of the form: c=a+bC1/2+dC+eC3/2. Also, the dependencies of concentration on the apparent molar compressibility jK are presented.
