An ultrasonic study has been made on solutions of lanthanum(lll) chloride i
n water and in different proportion of (1%, 2.5%, 5% and 10%) maltose-water
mixture at 303.15 K to evaluate various acoustic parameters, viscosity, co
nductance and apparent molar volume. The results are discussed here in term
s of ion-solvent, ion-ion interaction and of structural effect on the solve
nt in solution. (C) 2000 Elsevier Science B.V. All rights reserved.
