Solubility of a subsanece is it's maximum amount that can be dissolved in a fix/specified amount of solvent.
When solid Solute is added to solvent, some solute dissolved and it's concentration increase in solution. This process is known as Dissolution.
Some solute particles in solution collide with the solid solute particles and get separated out of solution. This process is known as Crystallisation.
At the dynamic equilibrium concentration of solute in solution willl remain constant at given temperature and pressure.
At point equilibrium, No. of solute particles going into Solution will be euual to solute particles separating out.
Saturated Solution: Solution in which no more solute can be Dissolved at the same temperature and pressure.
Unsaturated Solution: solution in which more solute can be dissolved at same temperature and pressure.
(Solid in Liquid)
Effect of Temperature - Pressure does not have any significant effect on solubility of solids in liquids because solid and liquid both are incompressible.
Factors Affecting Solubility Of Gas In Liquid
1. Nature of gas:- Gases which can be easily liquified, are more soluble in common solvents.
2. Nature of solvent:- Gases are capable to forming ion in aqousous solution are much more soluble in water than in other solvent.
3. Temperature:- The solubility of gas in liquid decrease wuth increase Temperature.
4. Pressure:- The solubility of a gases increase with increase in pressure.
