· Hydration is a process by which each ion is surrounded by a number of water molecules with an oppositely charged pole of solvent water oriented in the direction of the ion concerned Ion-dipole and ion-induced dipole forces operate much like dipole-dipole and induced dipole-dipole interactions,
The positively-charged side of the water molecules are attracted to the negatively-charged chloride ions and the negatively-charged side of the water molecules are attracted to the positively-charged sodium ions, Essentially, a tug-of-war ensues with the water molecules winning the match, Water molecules pull the sodium and chloride ions apart, breaking the ionic bond that held them together, After the salt compounds are pulled …
· The strength of ion-dipole attraction depends on the magnitude of the dipole moment and on the charge density of the ion, This latter quantity is just the charge of the ion divided by its volume, Owing to their smaller sizes, positive ions tend to have larger charge densities than negative ions, and they should be more strongly hydrated in aqueous solution, The hydrogen ion, being nothing more than a bare proton of extremely small volume, has the highest charge density of any ion

Ions Un ion est un atome ou une molécule qui a soit gagné ou perdu un ou plusieurs électrons le nombre de protons demeurant fixe Un ion de charge positive est appelé cation alors qu’un ion de charge négative est un anion © Hubert Cabana 2011

L’interaction ion-dipôle et l’hydratation des ions en solutions L’interaction ion-dipôle résulte de l’attraction d’un anion orientée par la charge partielle positive d’un dipôle ou de l’attraction d’un cation orientée par la charge partielle négative d’un dipôle, L’énergie potentielle est négative et augmente à l’inverse du carré de la distance comme l’indique la formule suivante :
Intermolecular forces are the forces which mediate interaction between molecules, including forces of attraction or repulsion which act between atoms and other types of neighboring particles, e,g, atoms or ions, Intermolecular forces are weak relative to intramolecular forces – the forces which hold a molecule together, For example, the covalent bond, involving sharing electron pairs between atoms, is much stronger than the forces present between neighboring molecules, …

Molecule-Ion Attractions This is how water and ions attract The hydrogen’s of water align themselves towards the negative ion anion surround it and takes it away, If the ion is a positive ion a cation the oxygen of the water align themselves towards the ion surround it and takes it away back to Bonding Links, Chemical Demonstration Videos

· Étant donné que les ions sont maintenus ensemble par des forces électrostatiques ils sont beaucoup plus stables que les molécules formées par des liaisons covalentes En raison des forces d’attraction élevées entre deux ions ils ont plus d’énergie de réseau que les molécules liées par covalence,

42 lignes · L’attraction électrostatique entre des ions de charge opposée est elle toujours favorable Le bilan de la formation d’une liaison ionique est donc favorable pour la combinaison d’un atome perdant facilement un ou des électrons potentiel d’ionisation faible avec un autre atome possédant une affinité électronique élevée Autrement dit la combinaison la plus favorable est celle d’un non-métal d’

· Ion-Ion attractions occur in a sample of ionic compounds, This is the strongest type of attraction because there aren’t partial charges, but instead full charges on the ions, An example of an ion-ion interaction would be NaCl being attracted to other NaCl molecules to form a crystal lattice,
