Hydrated sodium ion

WebHydration is an exothermic process. Figure: Dissociation occurs as ionic bonds in NaCl are broken. Energy absorbed must exceed the ionic compound’s lattice energy. This is followed by the hydration of Na + and Cl –. Hydration involves formation of ion-dipole forces which release energy. Web3 okt. 2024 · Ions and their surrounding water molecules (so-called hydration sphere) can become so closely associated with each other that they may resemble a new species with unique properties, such as structure, size, and mobility. These properties may be quite different from those of isolated ions.
