Ion-Ion interactions

Hi,

I feel like we didn't really touch on ion-ion interactions much in lecture. I was confused as to whether ion-ion interactions is the attractive force between the ions themselves or between ionic compounds? For example, is it the interaction between Na+ and Cl- ions, or is it the interaction between NaCl compounds?

Thank you!

Ion- ion interactions would be the attractive force between two ions like Na+ and Cl-. It is the attraction between a positively charged cation and a negatively charged anion.

Also keep in mind that ion-ion interactions are much stronger than other interactions between ions and molecules.

Ion - Ion interactions are the interactions between anion and the cation.

the ion-ion attraction occurs between a cation and an anion. They are strong bonds.

It should be between the individual ions, so in this case, between the Na+ and Cl- ions. Technically, I think they would be the strongest type of bond in a vacuum, but it is weaker than covalent bonds in water.
