FACTOR AFFECTING SOLUBILITY OF A SOLID IN A LIQUID

 Solubility

Maximum amount of substance that can be dissolved in a specific amount of solvent at a specified temperature is called its solubility.

FACTOR AFFECTING SOLUBILITY OF A SOLID IN A LIQUID:

NATURE OF SOLUTE AND SOLVENT:

polar solute dissolve in polar solvent and non polar solute in non polar solvents.( i .e .,like dissolves like)

EFFECT OF TEMPERATURE

-IF THE DISSOLUTION PROCESS IS ENDOTHERMIC ,SOLUBLITY   INCREASES WITH RISE IN TEMPERATURE .

-if dissolution process is exothermic ,the solubility decreases with rise in temperature.

EFFECT OF PRESSURE.

pressure does not have any significant effect on solubility of solid in liquid as these are highly incompressible.

FACTOR AFFECTING SOLUBILITY OF A GAS IN A LIQUID:

EFFECT OF PRESSURE:HENRY's LOW.

HENRY's LOW :-

state that partial pressure of the gas in vapor phase (p) is proportional to the mole fraction of the gas (x)in the solution "p =KH at a given pressure the lower is the solubility of the gas in the liquid.

EFFECT OF TEMPERATURE:

AS DISSOLUTION IS AN EXOTHERMIC PROCESS THEN ACCORDING TO LE CHATELIER'S PRIENCPLE THE SOLUBLITY SHOULD DECREASE WITH INCREASE OF TEMPERATURE.

RAOUIT'S LOW:

IT STATE THAT FOR A SOLUTION OF VOLATILE LIQUIDS, THE PERTIAL VAPOR PRESSURE OF EACH  COMPONENT OF THE SOLUTION IS DIRECTIY PROPORTIONAL TO ITS MOLE FRACTION PRESENT IN SOLUTION.

Y1 and Y2 are the mole fractions of the component 1 and 2respectively in the vapor pressure of the solution containing a non volatile solute is equal to the mole fraction of the solute.

	=	vapor pressure of the solution
	=	mole fraction of the solvent
	=	vapor pressure of the pure solvent
