Hydration Structures from Ab Initio Molecular Dynamics

WebThe dependence of hydration enthalpy on ionic radius, at constant charge, can readily be seen in Table 4.7 by looking down the members of a Periodic Table Group such as Li + → Cs + or Be 2+ → Ra 2+. The dependence on charge is qualitatively obvious on looking across Table 4.7, but is better demonstrated in the manner shown in Table 4.8. WebHydrates are substances that tend to associate with a fixed number of intact water molecules. Hydrates are almost always the (or one of the) cystal form(s) of the substance. We indicate a hydrate by appending the dot ( ·) symbol followed by the number of water molecules, like A x B y · nH 2 O, where n is the number of waters. We use the prefixes …
