he just teaches better than all the school material and teachers that I've had. it's been 7 years and this is still the best series for general chemistry
I left school at 16, returned as a mature age student and have now found myself starting med in feb. Having little background in chem/bio, your material is absolutely priceless. Thank you!
Take this and add the physical aspect of the actual visual application of the chemicals and chemical reactions, then you'll really have the ultimate course. I think too many people don't enjoy chemistry because it lacks too much of the actual visual aspect of seeing the chemicals react. Visual makes the theories come alive
I love your videos but I think you are wrong in the last example. Sulfuric acid is strong only in the first degree of dissociation (first hydronium ion). For the second degree of dissociation it is very weak so you should not take two times hydronium ions in the last example.
@@SaraRandall43 You can't do that. Imagine, for simplicity, that you have 100 molecules of H2SO4, they all dissociate completely (strong acid) to 100 H and 100 HSO4 but only 1/100 of HSO4 (weak acid) dissociate into H and SO4. Then you have only 101 H, 1 SO4 and 99 HSO4. Not 200 H and 100 SO4.
The equation is also unbalanced lol. Great video overall though. Love this channel, but he should make a side note correcting the error that should show conservation of mass.
Thank you very much of your wonderfull teaching. But I think you made a mistake in second one(calculating the ph of NAOH). The log0.28 is equal to _0.55 not 1.55.
You're videos are wonderful and very informative, but I don't think your dissociation of H2SO4 is correct. You can tell at first glance merely by the fact that the equation is not balanced. Someone already commented here that it has to do with the second dissociation being weaker. Please update this video and/or change it because students who are new to chemistry rather than reviewing could easily be confused by this mistake. Thanks, and thank you for all you do because it is awesome!

hows med skl
This video series is an absolute gem. Thank you, and please keep it up. Learning so much, and the pace is spot on.
Man I haven't taken a chem class in 6 years! You guys are helping me alot!

I’m solving it by myself just because of your help thank you sir you made it easy ❤
dude. thanks for being the best teacher ever.

I think he combined both steps of the dissociation into 1 step, hence the 2H3O.

Technically the first ionization constant of a dibasic acid will be very much greater than the second ionization constant.
These videos are really helping me thank you so much! Can you please also do some videos about chemicals reactions?
Excellent
How do we know how a polyprotic acid would donate its protons, what makes them differ in the way they donate protons?
Thank you very much of your wonderfull teaching. But I think you made a mistake in second one(calculating the ph of NAOH). The log0.28 is equal to _0.55 not 1.55.
How do you do these ph log calculations without calculator for MCAT purpposes? Good video, very informative.
