    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!

    • @cecillmk
      @cecillmk 3 года назад

      @@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!

    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

    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-) ?

    • @yingjun1555
      @yingjun1555 2 года назад

      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.
