How is it possible that the solubility increases with increase in size of the ion?
Dear Student,
The interionic distance of small ions is very less due to which they have strong attractive forces. More energy is required to overcome these attractive forces. However, with large interionic distances, it is easier to overcome the less attractive forces in case of larger ions.
Therefore, solubility increases with the increase of the size of the ion.
