Define a solution. Describe how an ionic solute such as NaC1 dissolves in water to form a solution. How are the strong bonding forces in a crystal of ionic solute overcome? Why do the ions in a solution not attract each other so strongly as to reconstitute the ionic solute? How does a molecular solid such as sugar dissolve in water? What forces between water molecules and the molecules of a molecular solid may help the solute dissolve? Why do some substances not dissolve in water at all?

Interpretation:

A solution is to be defined. The dissolution of an ionic solute such as NaCl in water to form a solution is to be described. The reason for, the strong bonding forces are overcome in a crystal of ionic solute during the formation of a solution,, is to be explained. The reason for the ions in a solution not attract each other so strongly as to reconstitute the ionic solute is to be explained. The reason for a molecular solid such as sugar dissolve in water is to be explained. The forces between water molecules and the molecules of a molecular solid that help the solute dissolve is to be describe. The reason for some substances not dissolve in water at all is to be explained.

Concept Introduction:

A solution is made up of mainly two components one is solute and other is solution. Any solute and solvent will form a solution is depend on the “like dissolve like” principle. The polar solute only dissolve in polar solvent and a non-polar solute only dissolve in a non-polar solvent.

A solution is represented as a homogenous mixture of solutes and solvent. The polar solute can only dissolve in polar solvent and a non-polar solute can only dissolve in a non-polar solvent. The ionic solids are polar in nature and water is also polar in nature that is why an ionic solute such as NaCl dissolves in water to form a solution. The ionic solute and water can easily interact with each other. The strong bonding forces in a crystal of ionic solute overcome during the formation of the solution because the energy of solvation of an ionic solute is sufficient to overcome the ionic bonding force. The water molecules surround the ions in a solution that is why the ions do not attract each other so strongly as to reconstitute the ionic solute. The arrangement of water molecules around the ions of NaCl is represented as,
