Question

Ions interact with water molecules via ion-dipole interactions. Stronger the ion-dipole interaction (lower the

potential energy/enthalpy) greater the thermodynamic stability. Let’s think about the relationship between charge density of the ion and the strength of the ion-dipole interactions

Arrange the following ions from weakest (1) to strongest (4) ion-dipole interactions

1 = weakest, 4 = strongest
