Conductivities of the Ternary Systems Y(NO3)3+La(NO3)3+H2O, La(NO3)3+Ce(NO3)3+H2O, La(NO3)3+Nd(NO3)3+H2O and Their Binary Subsystems at Different Temperatures

Viscosities of the Ternary Systems Y(NO3)3 + Ce(NO3)3 + H2O, Y(NO3)3 + Nd(NO3)3 + H2O, and Ce(NO3)3 + Nd(NO3)3 + H2O and Their Binary Subsystems at Different Temperatures and Atmospheric Pressure

“…Y­(NO 3 ) 3 ·6H 2 O (with a mass fraction purity of 0.9999), Ce­(NO 3 ) 3 ·6H 2 O (with a mass fraction purity of 0.9999), and Nd­(NO 3 ) 3 · x H 2 O (with a mass fraction purity of >0.99) were supplied by Shanghai Aladdin Reagent Co., Ltd. The binary solutions were prepared by the method of Spedding et al Therefore, each rare earth nitrate was dissolved into double-distilled deionized water to prepare the stock solution. , The resulting solutions were adjusted to their equivalent concentrations with dilute HNO 3 solutions and then reheated and readjusted until stabilized. ,, The molalities of rare earth nitrate stock solutions were analyzed by both ethylenediaminetetraacetic acid (EDTA) ,, and sulfate methods. ,, The stock solution concentrations were determined with an accuracy of ≤0.10 %. ,, Secondary stock solutions of low and moderate concentrations were prepared from weighed quantities of a primary stock solution and double-distilled deionized water using a Sartorius CT225D balance with the precision of ± 5·10 –5 g. ,, The ternary solutions were prepared by mixing the binary solutions (the mass of each binary solution is more than 20 g) . The uncertainties in the compositions of the prepared solutions due to errors in the weights of binary solutions were estimated to be less than ± 5·10 –5 mol·kg –1 .…”
