I had trouble understanding this at my lectures in University. Thank you so much it was perfectly simple and understandable explanation.
Thanks
Muy buen video, gracias por compartir el conocimiento.
Thank you. Well explained, Sir.
You are welcome
That's so interesting Professor. I need for my new youtube video. Thanks for your explanation👍👍😍😍
Why did you stop
can you do a video about activity?
Thanks for the explanation!
This is how real chemist should learn or else they will be more like memory science biologist . Thanks for correlating maths and chemistry..
Thanks for the explanation!
How is E, found for equation 2? I cant find it in any tables..
Can I ask a quick question? How to we know at which potential a real corrosion reaction will occur? For instance, in natural pH 7 water, how we know if Cu will form Cu2O, Cu(OH)2 or Cu(s)? cause it all depends on the potential, thank you!!!
@@dylanjayatilaka8533 thank you! I've checked the lecture while still wondering lets say, If I put Cu in water (pH =7), how would I know which electrochemical potential it will be and which product will it form? which equation should I check cause there are many reactions involved. Thank you!
@@dylanjayatilaka8533 Thank you for the reply! I will try to learn more about it. So when we have a Pourbaix diagram, lets say just the Cu or Fe in water, and I know the pH value, is there anyway to 'predict' the reaction happens in the solution without doing the actual experiment? Or do we have to measure the OCP of reaction to understand the electrochemical potential of the reaction happened on the Cu/Fe surface to know which region it falls? Because even we now the pH of solution, the electrochemical system may operate at a specific potential value right? Is it the OCP value or anything we can calculate? Thank you!
Thank you!
Thank you, very nice explanation of the stability diagram.
Sadly, I can't find the simulator on the website.
Good video thank you.
Sir what are the another examples for pourbaix diagram except iron please tell me sir...
your the MVP,
Why certain Poubaix diagrams such as FeCO3 and FeS2 have a curve line, instead of a linear/straight line?
Thank you so much!
Nice video!
What does stable mean?
awesome video
Which book to refer
Thanks Dylan!
Very helpful
thank you very helpful
Hello sir thank you so much for your very important and clear lecture. I am a phD student and I am wondering how can we do it experimentally in lab to produce data ? What kind of tools can we use?
you can use HSC or other programs to create one based on the thermodynamic data (delta G mainly) at least at standard temp and pressure
I saw for the first time in my MCAT prep-course and I was so thrown off by it. Thank you for the thorough explanation.
Very helpful lectures!!!
A bit confusing.... This is about Astatine or Arsenic?
Where did you get 10^-4.95 from? What are the individual values of Kh and pco2 used to get that answer?
this is really awesome for me thanks <3
daium perfect thanks !
Just one question: in that line where it says: [B] >> [A] --> E << 0 Should it not be therefore: [A] is unstable above the line, [B] is unstable below or in other words: B ist stable above, A below? Should it not be the opposite of [A] >> [B] --> E << 0 where you say: A is stable above, B below? Thanks in advance
Due to your explanation I was finally able to understand it! Thank you so much! Greetings from Germany
Great video
Can you upload video on adsorption isotherm.
Thanks for explaining I wasn't clear earlier

I needed this help for the MCAT. Thanks for making the video. Helped a ton!
I guess I am kinda randomly asking but does anyone know a good site to stream new movies online ?
@Lee Wesley ehh I'd suggest Flixportal. You can find it on google =) -atlas
@Atlas Asher Thank you, I went there and it seems like they got a lot of movies there :) I appreciate it!
@Lee Wesley glad I could help xD
Nicely done!
Thank you for the video. My prof rushed this topic and the whole class didnt seem to get it. Now me and a few friends do! Thanks again!
Thank you for this video.
407000/273.15 is NOT 109!
Thanks a lot! Great explanation! :D
can you explain why the second equation must be h2co3 and not hco3- ? doesnt the hco3- which is produced in first step react with water to give co32- (charge 2-) ?
This equation is try to show how much final proton amount is generated from HCO3-. Because we start with HCO3- (in form of NaHCO3), then we exam how much protons can be released (give H away into the solution) from it, and how much can be absorbed (take H from it). When one h2co3 is formed, it takes one proton away; when co3-- or OH formed, they give one proton out respectively. So if you drop some NaHCO3 into water, the final change of [H]=[OH]+[CO3--]-[H2CO3], and this is equivalent to the equation you asked. Hope this helps.
Thank you!
Any lecture for explanation of Evan Diagram ? Thank You
Edeleanu-Evans?
Nice sir
