daniellao Posted May 8, 2008 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?
CaptainPanic Posted May 13, 2008 Posted May 13, 2008 Could you explain the concept of "solubility in the gasphase"? As far as I know all gases mix with each other in all compositions, and therefore nobody ever bothered to define a solubility in air. But I guess you meant the solubility of oxygen in water? I am not sure which method you use (there is more than 1), but I always like the linear ones (Raoult and/or Henry)... the magic word here is "linear". Hope that the hint is clear enough.
asecco Posted May 17, 2008 Posted May 17, 2008 You mean solubilty IN WATER at such gas composition? Right?
