State Henry's law and mention some important applications.

Explanation

Henry law `:` It states that the solubility of a gas in a liquid is directly proportional to the presence of the gas.
Henry's law finds several applications in industry and explains some biological phenomea. Notable among these are `:`
`a.` To increase the solubility of `CO_(2)` in soft drinks and soda water, the bottle is sealed under high pressure.
`b.` To minimize the painful effects accompanying the decompression of deep sea divers, oxygen diluted withe less soluble helium gas is used as breathing gas.
`c.` In lungs, where oxygen is present in air with high partial pressure, haemoglobin combines with oxygen to form oxohaemoglobin. In tissues where partial pressure of oxygen is low, oxohaemoglobin releases oxygen for utilization in cellular activities.
