: located or acting between ions the observed interionic distances the effective interionic force.

What is Interionic force?

Interionic Attractions are when an ion is surrounded by an ionic atmosphere which has a net charge opposite for its own. For example an anion would be completely surrounded by ions mostly composed of cations and a cation would mostly be surrounded by ions of anions.

What is inter ionic distance explain with example?

The inter-ionic distance is the distancebetween ions; for example, you could measure this in a crystal structure of a protein if ions are bound.
