Henary's Law

Hello everyone, 

Today i am going to explain about HENARY'S LAW.

HENRY'S LAW : 

According to henary law solubility pf a gas in liquid which is measured in terms of mole fraction at a particular temperature is directly proportional to pressure exerted by the gas.

                                            

.                                     k_{H = Henary's law constant}

Characteristics of Henary's law constant : 

-> Unit of henary's law constant = atm , pascal

-> Henary's law constant depends on nature of solvent at fixed pressure.

LIMITATION OF HENARY'S LAW :- 

1.) Gas must not react with solvent.

2.) The concentration of solutions should not be high.

3.) There should be no dissociation or association of gas molecules.
