摘要：

The viscosity of dilute aqueous solutions of K-3[Al(ox)(3)]. 3H(2)O, K-3[Fe(ox)(3)]. 3H(2)O, K-3[Co(ox)(3)]. 3H(2)O and K-3[Cr(ox)(3)]. 3H(2)O complexes, as well as K-2(ox). H2O, were measured between 15 and 35 degrees C. Those of CoCl2, 6H(2)O, FeCl3, Al-2(SO4)(3). 18H(2)O, and CrCl3. 6H(2)O were measured at 25 degrees C. These data were analyzed by the Jones-Dole equation. The ionic B coefficients of the above complex anions were discussed in terms of ion-solvent interactions and the overall change in Delta B associated with complex formation.
