Solubility of Gases in Water (O2, N2, etc.)

In this video we'll look at the solubility of gases in water. First we'll look at a diagram showing how gases like O2 and N2 dissolve in water. Next we'll look at a computer animation that shows why less gas is dissolved in water as the temperature increases.
Gases can enter water by agitation (shaking it up so it mixes and the gas can dissolve more readily due to increased surface area and mixing) or by diffusion due to the random motion of gas and liquid molecules. Either way, gases like N2 and O2 are soluble in water.
Oxygen gas is particularly important on earth. The amount of oxygen dissolved in water is necessary for aquatic creatures, like fish. As temperatures increase the amount of oxygen dissolved will decrease. This limits the amount of O2 available for aquatic life.

Great video! Question about the location of the gases when they dissolve in the water. I remember my prof saying something about "interstitial spaces/sites" is what allows them to reside in water, but I can't seem to find anything on google that mentions this term in relation to gas solubility (only physiology references). Is that the term that we would use or is there another better phrase?
EDIT: I think he may have been conflating that term with its application in solid chemistry, how we have interstitial alloys where smaller atoms are able to exist between other atoms (in the interstices) in a crystal matrix.

I'm glad we took a look at that "grap"

[@k_clack]

Great explanation!

[@youtubeyoutube8754]

Keep up these great videos. I like it how you make videos on specific reactions and topics

[@wbreslyn]

Thanks, will do!

[@damonwayne7760]

really cool and great explanation

[@wbreslyn]

Thank you!

How come Gases stay inside the liquid even though gases are far less dens? I been taught that things that are less dens go up.

Thanks you so much ❤

[@aaryanpanigrahi7925]

But why do water molecules stick to each other?
As far as I know, surface tension decreases with temperature. And if you think about it, upon heating water becomes vapour, so they definitely don't stick together...

I am trying to understand how free protons in an acidic solution are different than hydrogen dissolved in water. Is it that the hydrogen atom keeps its electron?

[@aaryanpanigrahi7925]

Good question.
Hydrogen dissolved in water is still H2, or H-H (two hydrogen atoms covalently bonded). It's pretty much the same as the hydrogen gas as a gas in a tank, which is not acidic because covalently bonded H-H is pretty stable (No Anti-bonding orbitals, wrt Molecular Orbital Theory)
In an acid, say HCl - the hydrogen is bonded with an ionic bond, to a more electronegative atom. But even then, HCl gas is not acidic. It becomes acidic only in an aqueous solution, where the polar water molecules help H+, and Cl- to exist as separate ions in the solution - Only such an H+ ion, (without its electron, and free in a solution) will cause acidity.
Thank You.

If the solubility of carbon is more than oxygen so it would be more dissolve in blood than oxygen. Isn't it?

[@payalchandra3962]

Partial pressure of O2 is more than that of CO2 in lungs

[@Ramiromasters]

Can heat remove dissolved gases as good as a vacuum chamber?

[@wbreslyn]

That, or heating, is probably the best way.

[@aaryanpanigrahi7925]

I think a vacuum chamber is the best way, for solubility is directly proportional to the vapour pressure. But in the case of temperature, as you can see, the slope approaches zero at some solubility - that can be brought down with low pressure - irrespective of the temperature.

[@jesusshuttlesworth6834]

So essentially that's why cold water can gather much more oxygen as well as carbon dioxide?

[@mangai3599]

But I have the doubt "what does it mean that some gas is soluble in water?"; I mean I know how NaCl gets dissolve in water. How a gas dissolve in water???

[@alissa9821]

WAYNE I LOVE YOU

[@wbreslyn]

😎

[@Ajay_Verma19]

Can you explain everything in hindi

[@justvideos9424]

very helpful thenk you

[@wbreslyn]

You're welcome!

[@onatgecikligun4697]

Hmm that's why we drink cold coke better than warm coke :)

[@wbreslyn]

That does make sense! Once you opened the bottle the gases will leave the warm coke much quicker.

Watch from here...trust meh

[@wbreslyn]

Yeah, that's where the simulation/visualizations are really good!

[@yasyasmarangoz3577]

Thanks
