What occurs on the molecular level when an ionic compound dissolves in water?

Short Answer

Expert verified

When an ionic compound dissolves in water it becomes dissociated polar part gets attracted toward the water molecule.

Step by step solution

01

 Step 1: Identification of the dissociation of ionic compounds

When ionic compounds dissolve in water, it dissociates into ions by breaking their ionic bond when the strong electrostatic force of attraction generates by the molecules of water and ionic compound since both the ionic and water molecules are polar in nature and the attraction between the ions and water molecules is much stronger than a compound itself.

02

Determine the solubility of ionic compounds in water molecules

Now the molecules of water surround the ions of the ionic compounds to stabilize the ion in such a way that the negative charge of water surrounds positive ions and the negative part surrounds the positive ions as shown in fig given below:

This states that the ionic compound dissolve in the water molecules.
