Under atmospheric condition solubility of has to be determined.
Solubility is said to be one of the chemical property which implies that at equilibrium the maximum amount of solute dissolved in the solvent to gives solution called ‘saturated solution’.
Henry’s law states that dissolved gases in liquid are directly proportional to the partial pressure of the gas over the solution.
is molar concentration of dissolved gas
is proportionality constant
is partial pressure of the gas over the solution
