Henry's law may also be states as:
The solubility of a gas in liquid at a particular temperature is directly proportional to the pressure of the gas in equilibrium with the liquid at that temperature.
The solubility of a gas in liquid at a particular temperature is directly proportional to the pressure of the gas in equilibrium with the liquid at that temperature.

According to Henry's law at constant temperature the solubility of gas in liquid is proportional to the partial pressure of the gas.
i.e. At constant temperature increasing the partial pressure will increase the amount of dissolved gas.
Partial pressure of the gas = KC.
partial pressure of the gas = KX.
K = Henry's constant.
X = mole fraction of the gas in liquid.

Henry's law is one of the gas laws formulated by William Henry in 1803. It states:
"At a constant temperature, the amount of a given gas that dissolves in a given type and volume of liquid is directly proportional to the partial pressure of that gas in equilibrium with that liquid."
An equivalent way of stating the law is that the solubility of a gas in a liquid is directly proportional to the partial pressure of the gas above the liquid.
An everyday example of Henry's law is given by carbonated soft drinks. Before the bottle or can of carbonated drink is opened, the gas above the drink is almost pure carbon dioxide at a pressure slightly higher than atmospheric pressure.
The drink itself contains dissolved carbon dioxide. When the bottle or can is opened, some of this gas escapes, giving the characteristic hiss (or "pop" in the case of a sparkling wine bottle). Because the partial pressure of carbon dioxide above the liquid is now lower, some of the dissolved carbon dioxide comes out of solution as bubbles.
If a glass of the drink is left in the open, the concentration of carbon dioxide in solution will come into equilibrium with the carbon dioxide in the air, and the drink will go "flat".
