The Factors Affecting of Solubility


The Factors Affecting of Solubility: Solubility is a certain amount of dissolution of the soluble substance with a specific solvent in certain conditions .They are create the solution together.


Solubility constant is relatively low resolution of the ionic saturated solutions of the compounds used to for describe.
Salts of the resolution is for the constant, the maximum amount soluble in aqueous solutions. Resolution constant is a special case of the equilibrium constant. Describes the balance between dissolved and undissolved salt.

For a substance is dissolved in another substance of these compounds in the free energy of the system, the total free energy of the initial substances should be small.
No matter how great the change in free energy than the more soluble in each other.
Substance is for dissolved in another substance of these compounds in the free energy of the system's the total free energy of the initial substances should be small.



According to the Type of Solvent and Solute Substance : If Between of solvent and solute at the molecular structure similarity is the higher,the resolution is the higher too.Each substance is insoluble in each substance. Inorganic compounds are soluble inorganic compounds, organic solvents are soluble soluble in organic solvents.
Polar compounds are soluble in polar solvents, non-polar compounds are soluble dissolve in non-polar solvents
For example, naphthalene is insoluble in water but soluble in benzene. Similarly like dissolves.

Pressure: The pressure is not a big effect on solubility of solids and liquids.

Temperature: The temperature of solids and liquids, mostly with the resolution increases, the solubility of gases decreases with increasing temperature.

Common Ion Effect and Solubility : Ionic precipitate's one of the ions when the solid matter is added to a saturated solution of the solid matter's in the observed reduction in resolution.
