The water is in equilibrium with air at a pressure of  At . if the Henry’s law constants for oxygen and nitrogen at  are and respectively, calculate the composition of these gases in water

Answers (1)

We have been given that the water is in equilibrium with air at a pressure of 10 atm or 7600 mm of Hg.

So the partial pressure of oxygen :

and partial pressure of nitrogen :

Now, by Henry's Law :

For oxygen :

For nitrogen :

Hence the mole fraction of nitrogen and oxygen in water is  and  respectively.
