Ionic potential is the ratio of the electrical charge (z) to the radius (r) of an ion.[1]
As such, this ratio is a measure of the charge density at the surface of the ion; usually the denser the charge, the stronger the bond formed by the ion with ions of opposite charge.[2]
The ionic potential gives an indication of how strongly, or weakly, the ion will be electrostatically attracted by ions of opposite charge; and to what extent the ion will be repelled by ions of the same charge.
Millot (1970) stresses the importance of the ionic potential of cations to explain the high, or the low, solubility of minerals and the expansive behaviour (swelling/shrinking) of clay materials.[3]
It is also a measure of the polarising power of a cation.
Ionic potential could be used as a general criterion for the selection of efficient adsorbents for toxic elements.[4]
