explain the attraction of Na and Cl ions for water molecule
sodium chloride is an ionic compound. When sodium chloride (NaCI) is placed in water, it dissolves quickly. The adverse finish of water particles is drawn to sodium particles and the positive finish of water atoms is drawn to chlorine ions. In this Case, solute-solvent attractions are more in comparison with solute-solute interaction therefore solution of sodium chloride is formed. These attractive forces of water are stronger enough to overcome the attraction between Na+ and Cl- ions in NaCl
explain the solubility with reference to like dissolve like principle
General Principles of Solubility
The general, principle of solubility is "Like dissolves like". Its mean that two substances with similar intermolecular forces are likely to be soluble in one another. It has been observed that Ionic and polar solute dissolved in polar solvents. For example, Na2CO3 sugar and alcohol are polar and dissolved In water because water is also polar.Nonpolar solute dissolved in non-polar solvents. Such as oil and paints are non-polar, they are dissolved in either as both are non-polar. Similarly, waxes and fats break down in benzene and not in water.Nonpolar compounds are not soluble in polar solvents (water).
For Example, oil, petrol, benzene are non-polar, they are not dissolved in water because water is polar.
