Henry's Law is defined as
" At 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."
⇒p= kH C
Where p-- partial pressure of solute in the gas.
c--concentration of solute
.kH is Henry's constant.
Importance of Henry's Constant :1.To increase the solubility of CO2 in soft drink and soda water, the bottle is sealed under high pressure.When bottle is opened,under normal Atmospheric pressure, the pressure inside the bottle falls to atmosphere pressure and effervescence of CO2 gas is seen.
2 .During scuba diving, driver breathes in the compressed air from supply tank , more Nitrogen is dissolved in blood because of more pressure at depth
3. Henry's constant plays a vital role in environmental chemistry.

Explanation:
The knowledge of Kh value of a gas at a given temperature can help us in calculation of its solubility at that temperature. It is important to note that as the temperature increases the solubility decreases.
Its has several application based significance too-
1) Production of carbonated beverages.
2) Reduce Anoxia in climbers.
3) Avoid bends in scuba divers.
