These videos are so so helpful, I know you get appreciative comments all the time but it can not be stated enough how much of an impact you have on students and their grades, if I do well in my exams then you get half the credit (:

At 57:20, if you increase the concentration of Fe, the equilibrium would shift left therefore increasing the electrons in the system, wouldn't that make the electrode potential of Fe2+/Fe more negative and hence overall cell potential would be higher?
@bLue-xx1uy3 ай бұрын
Also increasing the concentration of Fe solid doesn't sound quite right, I think when we state that altering the concentration affects the E0 value: it is only about altering the concentration of the aqueous ion solution or the pressure if the system involves gases?

@FaizanA-mh4pd3 жыл бұрын
At 57:20, doesn't increasing the concentration of Fe cause the electrode potential to become more negative?

Your video is absolutely amazing! I can't thank you enough for all your hard work! I do have a question, so you mentioned that electrons will always flow from the most reactive metal to the least reactive metal. So I'm a little confused whether we look at them in terms of a reactive the metals are or in terms of e values?

These videos are very helpful thank you very much. I just have a question. what could they ask in an exam in the 1-3 marks questions on these topics. e.g. why is an excess of KI added? for redox and electrode

hi doe s anyone know why the electrons from from the anode to the cathode rather than the other way round?
@layanfiras75392 жыл бұрын
At the anode the compounds are oxidised so they lose electrons and at the cathode they are reduced so they gain electrons. So the electrons must be supplied by the ones losing electrons and so they move from the negative anode to the positive cathode
