X-ray and neutron diffraction studies on concentrated aqueous solutions of sodium nitrate and silver nitrate
Year: 1989
Type: article
Abstract: Neutron diffraction experiments have been conducted on 3.1 M (molar) solutions of 107 AgNO 3 and 109 AgNO 3 in heavy water, and the first-order difference method of isotopic substitution has been used to obtain the local structure around Ag (aq) + . The results of this work have been used in conjunction with those from an X-ray diffraction study of 3.1 M (molar) AgNO 3 and NaNO 3 , to establish the degree of structural isomorphism between Na (aq) + and Ag (aq) + . It has been shown that Na (aq) + and Ag (aq) + are sufficiently isomorphic to enable useful pictures to be obtained for both Na + hydration and Ag + -Ag + coordination. Comparison with previous results for the other alkali metal ions shows that, in terms of the strength of hydration, Na + is intermediate between Li + and K + .
