Question

Which of the following explanations accounts for the fact that the ion-solvent interaction is greater for Li than for K

Answer 1

Li+ has a smaller ionic radius than K+

and smaller molecules have more collisions/interactions between each other

What is ion-solvent interaction ?

In the case of ion-solvent interactions, the state in which the interac-tions exist is an obvious one; it is the situation in which ions are inside the solvent.

• Ions are charged particles, and charges interact with other charges. So there will also be ion-ion, as well as ion-solvent, interactions in the solution.

• In the process of solvation, ions are surrounded by a concentric shell of solvent. Solvation is the process of reorganizing solvent and solute molecules into solvation complexes.
