CHEM3006 - 31 - Pourbaix diagrams: how they work

[@annawalther8745]

Due to your explanation I was finally able to understand it! Thank you so much! Greetings from Germany

[@ardalan4348]

I had trouble understanding this at my lectures in University. Thank you so much it was perfectly simple and understandable explanation.

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!

Your video is really good! it explains porbaix diagrams very well no video on youtube to explain it properly a good work towards the path of education.looking forward to more videos on your side.

The info out there is really nasty and half baked.
Many thanks!

This is how real chemist should learn or else they will be more like memory science biologist . Thanks for correlating maths and chemistry..

Just one question: in that line where it says: [B] >> [A] --> E > [B] --> E

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?

[@xiaojingyang1483]

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

How do you calculate the pH when no e- are involved?

[@cecillmk]

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!!!

[@cecillmk]

@@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!

[@cecillmk]

@@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!
