Pressurizing Water: Effects on Air & Water

[Dave Klein]

If I take a bottle fill it 1/2 full with water and then pressurize the top portion of the bottle with say 350 p.s.i., compressed air on top. Will any of the properties of the air (nitrogen, oxygen, etc...), go into solution with the water (a hydrate), depleting any of my air volume?

Will the legnth of time this air-water contact occurs effect any saturation of the air into the water. And of course I would assume the contact area would be consistent to this absorbtion into the water.

Any ideas on where I could find additional information etc. I would appreciate it. Thank you.

Yes, the solubility of gases generally increases with pressure. This doesn't produce a vacuum, though. As the equilibrium is reached quickly, the duration of time matters little.
