Incredible videos supplied for free, just started grad school and these videos are more helpful than classes or textbooks in getting caught up in the field
Amazing content! I am concerned about the conductivity formula 4:05, particularly that Area is at denominator. It seems l/A is for resistance equation, but not for reciprocal conductivity. Am I right? thanks a lot!!!
Difficult to recommend a single text. I know that Oxford University Press have published a primer for electrochemistry, however I haven't read it so couldn't fairly comment. What I do know is that there are very few single books which completely cover electrochemistry. Early editions of Atkins Physical Chemistry (5th ed and earlier) have decent amounts on electrochemistry, and you can pick up a copy of those fairly cheaply second hand.
Great course, but you keep mixing conductivity and molar conductivity. This way it seems like the conductivity decreases with more ions and therefor water without any ions would conduct better. However, at low concentrations every mol of ions adds more to the conductivity than a mol at very high concentration.
Good point! yes, it's easy to sink into a way of communicating. Yes, the absolute conductivity decreases with concentration, but the _relative molar conductivity_ (conductivity per mole of solute) increases.
Great video, but the discussion on how to calculate molar conductivity of various species seems to be a sidetrack. I wish there were more discussion on how this topic is relevant to electrochemistry, or real life problems.
I'm sorry things weren't more clear. Basically, without ions in solution, we can't have electrochemistry. So how ions behave in solution is really important; they don't behave ideally, and the concentrations of ions in solution really affects the electrochemical measurements we can make. Hope that helps,

You're also great at posing and responding to all the rhetorical questions I'm thinking
great video! its very helpful to understand the concepts im currently studying
Your videos are very clear and concise. Well done!

Thanks for very helpful videos!
Very well explained, thank you :)
This is great explanation , so clear !!!! Could you recommend a book on the introduction of electrochemistry ?? Thank you
