Viscosities were measured for the ternary systems Y(NO3)3+La(NO3)3+H2O,La(NO3)3+Ce(NO3)3+H2O,and La(NO3)3+Nd(NO3)3+ H2O and their binary subsystems Y(NO3)3+H2O,La(NO3)3+H2O,Ce(NO3)3+H2O,and Nd(NO3)3+H2O at 293.15,298.15 and 308.15 K.The results were used to test the applicability of simple equations for the viscosity of the mixed solutions.The predictions agreed well with measured values,implying that the viscosities of the examined electrolyte solutions could be related to those of their constituent binary solutions using these simple equations.
