Ionic compounds can be readily dissolved in water because the high dielectric constant of water screens and decreases the force between the oppositely charged ions.

Electrostatic force

Explanation :

Ionic compounds can be readily dissolved in water because of the high dielectric constant of water screens and decrease the Electrostatic force between the oppositely charged ions.

Since water is a polar molecule and has a high valued dielectric constant. Water makes a bond with ions when dissolved and reduces the electrostatic forces that hold in a solid structure.
