How does oxygen dissolve in water?
oxygen is a non polar molecule, o2, how would this dissolve in a polar solvent such as water. Dissolved oxygen is vital to life but how does it get there. what ion would the oxygen form to dissolve, O- or O2-?
Answers:
Water, as a polar molecule, induces an accumulation of electron density (dipole moment) at one end of non-polar gas molecules such as oxygen (O2 ) and carbon dioxide (CO2 ). The electron cloud of O2 is normally distributed symmetrically between the bonded O2 atoms. When the negative end of the H2O molecule approaches the oxygen molecule, the electron cloud of the O2 moves away to reduce the negative-to-negative repulsion. A dipole (a molecule with positive and negative charges separated by a distance) results in the nonpolar O2 molecule and causes O2 and H2O to become weakly attracted to each other. This intermolecular attraction between the oppositely charged poles of nearby molecules is termed a dipole- dipole force. The creation of these forces explains the mechanism by which gases dissolve in water.
too much smart people stuff..and way too many big words foe me man
the molecule do not change when dissolve in water, so the ion would be O
using large amounts of pressure
Water is the "universal solvent". it has both polar and non-polar attributes which allow it to dissolve both polar and non-polalr species.
Also, diatomic oxygen (O2) may not be classified as 'polar' but is can be polarized fairly easily, not to mention it's ability to form hydrogen bonds with the H atoms in water.
same way anything dissolves, the molecules mix with the H2O molecules, what you see isnt actually pure water, its water with other stuff floating between the molecules
Oxygen is only slightly soluble in water. If you bubble air through water, most of it passes through but very small amounts dissolve. Even things like oil and gasoline will dissolve in water in trace amounts.
