daniellao Posted May 8, 2008 Share Posted May 8, 2008 In 1 atm of pure oxygen, the solubility of O2 in water is 1.38x10^-3 mol/L at 25 degrees celcius. The mole fraction of oxygen in air is .210. If the atmospheric pressure is 1 atm, what is the solubility of oxygen in air at 25 degrees celcius? Link to comment Share on other sites More sharing options...

daniellao Posted May 8, 2008 Author Share Posted May 8, 2008 its exactly how the question is written, and how my professor gave it to me.... thats y i am very confused Link to comment Share on other sites More sharing options...
Mr Skeptic Posted May 9, 2008 Share Posted May 9, 2008 Looks like the question is about the solubility of oxygen in water at atmospheric concentration and pressure (as opposed to for pure oxygen). Link to comment Share on other sites More sharing options...
thedarkshade Posted May 9, 2008 Share Posted May 9, 2008 The solubility of oxygen in water decreases with the increase in temperature. This also affects water's ability of auto-purification. Link to comment Share on other sites More sharing options...
