    Good day sir, the videos are fantastc and I honestly can't put into words how much I appreciate them, thank you ever so much!
    I have a question, which videos should I be watching If I'm sitting the A2 modules of the old specification? I'm a little confused as these videos aren't labelled old or new spec.
    Thanks a tonne hope to see more great content from you! :)

    • @MrERintoul
      @MrERintoul  8 ปีที่แล้ว +2

      +James Rodrigo Look for the playlists. I've kept the playlists labelled as Unit 4 and Unit 5 so use the videos in there.

  • @thewhowhatwherewhyho

    My textbook says that H₂SO₄ is only a strong acid in its first ionisation:
    H₂SO₄ --> H⁺ + HSO₄⁻
    But for the second ionisation, the HSO₄⁻ ion is a weak acid and is only partially ionised:
    HSO₄⁻ H⁺ + SO₄²⁻
    So apparently you can't assume that a 0.1 mol dm⁻³ solution of H₂SO₄ = H⁺ concentration of 0.2 mol dm⁻³.
    However your video and the rest of the internet says otherwise ;__;

    • @MrERintoul
      @MrERintoul  8 ปีที่แล้ว +8

      You may be correct, however I'd stick with it being fully strong and diprotic.

  • @TheNathanael315
    @TheNathanael315 8 ปีที่แล้ว +4

    Great video, so happy you're uploading again. Would you be able to divide up the topics as they are on the spec? I know that the topics need to be divided up due to the larger amount of information in each topic, but it would be amazing if you could.

    • @TheNathanael315
      @TheNathanael315 8 ปีที่แล้ว +2

      Its a small issue, but I was just thinking that that organising my notes would be faster if you note in the description from which section of the specification that each of your videos refer to. For example your Buffers, Acids, Bases and pH and Kw and Bases videos are all from the section 3.4.3. If you put the section number in the description I would be much more confident that I haven't overlooked any of your videos for that particular section. Its probably a personal issue, love your videos, but it would be easier for me. Sorry for the inconvenience.

    • @MrERintoul
      @MrERintoul  8 ปีที่แล้ว

      Black Marvel I think I see what you mean. What I'm planning on doing is arranging all the videos by topic (have at look at my channel homepage and you'll see what I've done with the new specification videos). Would that help?

    • @TheNathanael315
      @TheNathanael315 8 ปีที่แล้ว +1

      Yeh, that helps a lot, final question, should i watch the 'new and old spec' videos as well as those in the unit 4/5 playlists that do not include the 'new and old spec' in the title? Also thank you for getting back to me so quickly its very appreciated.

    • @MrERintoul
      @MrERintoul  8 ปีที่แล้ว

      Black Marvel I would advise going by the playlists. Some of the new and old spec videos are for AS...

    Shouldn't the 2nd example be a -ve pH because when u put it into your calculator it gives a positive answer meaning you need to change it back to a negative

    If the answer is a minus, do you convert it to a positive number or leave it as it is?

    • @MrERintoul
      @MrERintoul  8 ปีที่แล้ว +9

      +TheLittlePinkyyy If you calculate a negative pH, LEAVE IT AS A NEGATIVE. It just means that the solution is very acidic.
