| dc.description | The method of X-ray diffraction with isomorphic substitution has been extended to aqueous solutions containing complex ions. In a study of isomorphism between NO<sub>3</sub><sup>-</sup>(aq), BrO<sub>3</sub><sup>-</sup>(aq) and ClO<sub>3</sub><sup>-</sup>(aq), it is found that the NO<sub>3</sub><sup>-</sup> and BrO<sub>3</sub><sup>-</sup> ions are isomorphic up to the level of the first-order difference indicating a similarity in their anion-hydration structure. Based on the isomorphism of these two ions, and because the water molecules are only weakly perturbed from their structure in pure water, a second-order difference calculation was made and the ion-ion pair correlation function of these two ions obtained. The results show that the most probable ion-ion separation is between 5 AA and 11 AA and the distance of closest approach is 4.8 AA. NO<sub>3</sub><sup>-</sup> and BrO<sub>3</sub><sup>-</sup> are found, however, not to be isomorphic with ClO<sub>3</sub><sup>-</sup>. |
