Explain the dissolution of a salt - use a diagram

Question 1

Intro statement - define

Answer 1

An Ionic compound such as PbCl2, are held together by ionic bonds.

Question 2

Dissolute in solution

Answer 2

Water molecules, which are polar, experience dispersion forces and hydrogen bonding. The polarity of water allows for electrostatic interactions between ions and water as shown in the diagram above.

Question 3

Results in the formation….

Answer 3

Results in the formation of ion-dipole bonds. Dissolition will occur when the ion-dipole ions are more energetically favourable than the existing ionic bonds and intermolecular forces between the water molecules.

Question 4

Thus,

Answer 4

this results in the water molecules forming hydration spheres around ions, allowing dissolved ions to be dispersed in solution.

Question 5

Thus,

Answer 5

this results in the water molecules forming hydration spheres around ions, allowing dissolved ions to be dispersed in solution.
