State Henry's law and mention its some important applications.

Explanation

Henry.s law states that, the mass of a gas dissolved in a given volume of the liquid at a constant temperature depends upon the pressure applied.
Mathematically, `mpropp` (at constant temperature)
Applications of Henry.s law are as follows :
(i) `CO_(2)` can dissolve in water to make carbonated water, e.g., `CO_(2)` in soft drinks.
(ii) `O_(2)` combines with haemoglobin to form oxyhaemoglobin (inside the lungs) due to high partial presure of `O_(2)` inside the lungs.
