      i am grade 7 and i study acid and base
      so i do not know h+ concentration

    Thanks for this great demonstration, it was helpful. Lemon and coffee showed similar acidic nature, not all acids have same outcome to our body, please share a video on which acids are good to consume and which are not. Waiting for your response.

    Soda Pop was much more acid than I was expecting! Great video!

      @thomasgronek6469 6 лет назад

      Not only does the phosphoric acid play a BIG part, carbonic acid is also involved (not too much, I think a saturated solution yield a pH of about 5)

  • @alexandrupostole7234
    @alexandrupostole7234 7 лет назад +1

    The H+ concentration is the the number in the logarithm like this if im not mistaking:
    n=-log(10^-n) e.g. Soda Pop has the pH= 2,87
    2,87=-log(10^-2,87) , so the H+ concentration is 10^-2,87

    • @drumetul_dacic
      @drumetul_dacic 7 лет назад +3

      That is correct. In general: H⁺ = 10^(-pH).

    Great video, Thank you. You are the best, I haven't seen a video this good for a long time! pH=-log[H+], (I will put it in English: the negative log of the hydrogen ion concentration). Did I answer your question? Or does one need to use something like the Henderson/Hasselbach equation? [inverse log or negative log]?

  • @elbryan9
    @elbryan9 7 лет назад +6

    Just a suggestion but if someone has, "a big gap" in their knowledge of chemistry, it might be a good idea to define what an H+ ion is. But otherwise, very cool video!

    • @Socratica
      @Socratica  7 лет назад +5

      hehehe...can't teach them all of chemistry in one video! Maybe after this video, they can watch our more hard-hitting pH video with calculations - that one shows water auto-ionizing: bit.ly/1MjWY19

    How does one calibrate one of those ph meters? I don't like using random chemicals if I plan to use the meter with foods. Anyway to force something to a very particular ph? Distill the hell out of water? Also are bases slippery because it pulls fats from our fingers?

      @Socratica  7 лет назад +4

      I wouldn't eat something just because it was pH 7, no! :) Probably lots of toxic things are close to pH 7.

    • @Socratica
      @Socratica  10 месяцев назад

      What an interesting question! This tester works best with a liquid sample you can immerse it in. So unlikely, unless you could scrape up some of it and put it in water to dissolve it (measure how much water so you know how dilute it is) and then take the pH?

      @@thomasgronek6469 The window cleaner is considered a base (basic) because it has less Hydrogen ions (H+) than water, the lemon is considered an acid (acidic) because it has more H+ ions than water...hence the joke

    • @drumetul_dacic
      @drumetul_dacic 7 лет назад

      It means that it is a base with a pH of 8.

      @hpspspspsps5798 7 лет назад
