Hydration of ions
WebWhat happens when ions are hydrated? This process, in which either a positive or a negative ion attracts water molecules to its immediate vicinity, is called hydration. When water molecules move closer to ions under the influence of their mutual attraction, there is a net lowering of the potential energy of the microscopic particles. WebIt has been shown that there is a certain limiting value for the crystallographic radius which divides singly charged ions into hydrating and nonhydrating. 4. The structure of water is …
