Temperature and Gas Solubility

We know about solutions and solubility, but we have typically examined solid or liquid solutes dissolved in a liquid solvent. Did you know that gases can also be dissolved in liquids? Their solubilities depend heavily on temperature, so let's take a closer look at this relationship!

I love this style of making videos... No spoonfeeding, no beating about the bush just straight to the point explanations

[JamesKintner]

Seems like just yesterday you were helping me with my organic chemistry, now I need your videos for anesthesia school... Thanks Professor Dave!

[shae-fzuv]

he is a real scholar, a real scholar who knows his subject real deep and can explain stuff

[kishorekumarr]

hello sir im kishore from india im a big fan of ur lecturess

[abhiramsrivathsa]

very well explained. but where is comprehension?

1:36 why oxygen dissolve in water ? Bcs oxygen is non polar and it can make dipole-induced dipole interaction with water.

4: 35 solubitlity oxygen in trmperature normal (27⁰)

why does the solubility of CaSO4 decrease as temperature increases?? please help!

[saurabhjha]

You have explained the topic very well

[mrg]

Hello, thank you for your vedio, is there any book that describe gas solubility mechanism?

[brandonconnors]

Professor Dave you da shit. thanx for helping me learn and pass my chemistry course

[TheKinFly]

Thank you very much for your videos Prof. Dave. However I have a comment: I like your videos more when you talk more naturally (like your old Orgo videos). While still very informative, videos like this one end up sounding a bit monotonous.

Greetings from Brazil!

2:39 approximate these type of interactions. *what does that even mean??*
IM DYING HERE PLEASE HELP

5:11 - 6:01 - Prof. Dave keeping it real! #climatechangeisreal

So this means when we provide pressure to any system including lets say CO2 and water so more of CO2 molecules interacts with water hence saturating it right ?

[aycec]

I learn all sience here by your videos..then Books🙏🏻💜

[itsashepubg]

I think u would look adorable when you cut your hair and shave your beard..just wondering though... But this is the identity of Professor Dave soo... Cool

[cheraddysujatha]

Hii sir u lectures r really very useful for me I have a doubt.. u r saying soulbility depends on dipole dipole interactions moment is a property of a molecule then howcome pressure can increase the soulbility means how can it exactly effect the dipole nature of

Why is methane more soluble than oxygen as the gas solubility graph shows? That doesn’t make sense to me. Sure, methane is more polar than oxygen in isolation. But in water, the oxygen gets polarized via the dipoles of the water molecules. Hydrocarbons tend to not get polarized in this manner as the carbon is not all that electronegative, leading to decreased solubility with more carbons. In fact, I’ve only seen hydrocarbons get polarized in 2 ways, those being:

1) Addition of halogens, halogen replaces hydrogen and the molecules become polar and unreacted molecules still get polarized by the presence of halogen, small amount of acid forms in the process
2) Double bond reaction with water, oxygen bonds to the carbon in the double bond and forms an alcohol, which is polar, a hydrogen gets kicked off the water molecule

So why would methane be more soluble than oxygen in water?
