What is Solubility?
Solubility is the maximum amount of solute which can be dissolved in 100 gm of Solvent at a particular temperature.
Note : Solubility is defined with respect to solvent. Solubility of salt in water will be different from Solubility of salt in Oil.
Also, note that while mentioning Solubility, we have to mention temperature was well
Example
Solubility of Salt is 36gm (at 20 degree celsius)
-
It means maximum 36 gm of salt can be dissolved in 100 gm of water at 20 degree celsius
Effect of Temperature on Solubility
-
In case of
Solids
dissolved
in Liquids
- If we increase the temperature, solubility increases
- If we decrease the temperature, solubility decreases
-
In case of
Gases
dissolved
in liquids
- If we increase the temperature, solubility decreases
- If we decrease the temperature, solubility increases
Effect of Pressure on Solubility
-
In case of
Solids
dissolved
in Liquids
-
Change in pressure
doesn't change
the solubility

Change in pressure

In case of
Gases
dissolved
in liquids
- If we increase the pressure , solubility increases
- If we decrease the pressure , solubility decreases
