    I would say just wow. So simply explained and in a relatively short time. Chemistry has been a nightmare for me but such videos make it look easy. Thanks a lot.

    This video is hands down the best pH video on RUclips. It teaches you pretty much everything in 8 minutes! I overlook videos like these because they have much less views than the rest so I assume that they aren't that great- I was wrong.

    This video made me realize I'd learned pH the wrong way, in high school. Consequently, I struggled with acid-base chemistry, and chemistry as a subject area became something to be avoided. Thank you for taking the blinkers (blinders) off!! GREAT video!!

    1. Ph is a way to measure the strength of acids and bases
    2. An Arrhenius acid is a substance that generates H+ ions when dissolved in water
    3. Bases when dissolved in water generate OH-
    4. We use the Arrhenius definition when dealing with aqueous solutions of substances
    5. The brønsted-Lowry is based on the transfer of a proton, an H+ion, from one substance to another
    6. A brønsted-Lowry acid releases a proton
    7. A brønsted-Lowry base accepts a proton
    8. The brønsted-Lowry definition does NOT depends on substances being dissolved in water
    9. A strong acid more readily donates a proton than a week acid
    10. A strong base more readily accepts a proton than a weak base
    11. The pH scale was suggested by Søren Sørensen
    12. It’s a logarithmic scale that makes it easier to write the very small amounts of H+ ions that are produced by acids and bases
    13. The equation is: pH=-log[H+]
    14. Water is neutral
    15. All substances that have a pH of seven are neutral

    I don't understand.
    As far as I understand ionization, it is the loss or gain of electrons therefore changing the charge of the atom. Right?
    How do protons come into play in this definition of pH?

  • @christopherscottgutierrez3323
    @christopherscottgutierrez3323 Год назад

    the volume of the acid is the same mole for the absorbed substance, the acid level will drop with other moles that are not absorbed as well or vise versa absorb same or better it will go up, like water you put your finger in it it will drop acidic level due to other moles that are not absorbed as well for the human body, if you osmos the water it will go up in acid level if you osmos right for the human body abosorbtion

    02:32 But doesn't it produce the "basic" OH⁻ ion at the same time? :q Because if that's the case, this animation/explanation wouldn't explain the _excess_ of H⁺ ions in the solution, would it?
    04:40 Why are the concentrations being multiplied here and not added?

    I have some practical questions: can we change the pH of something? How? For example, if we mix baking soda on a glass of lemon juice it becomes more neutral? And, doesn't the pH of the land where the lemon was harvested influence the pH of the lemon itself?
    I'm far from being a scientist or even having a scientific mind, I'm just curious.

    • @joannescalzitti9959
      @joannescalzitti9959 5 лет назад +2

      You can change the pH by adding acid or base, depending upon whether you want to make something more acidic or basic. Neutralizing lemon juice with baking soda occurs because baking soda is like a towel that soaks up H+. This is possible because a base, by definition is an H+ acceptor and an acidic substance like lemon juice is acidic because it gives up H+. The pH of soil affects many things such as phosphate availability, but not the acidity of the lemon. A lemon is acidic because it forms a lot of citric acid.

    @ericferro510 6 лет назад +2

    Really, the best video on pH, but there was one thing that remained unexplained and I think it's of major scientific interest in what regards the study of acids and bases, it is: what's the physical and chemical properties and processes that produces the macroscopic phenomena of corrosion when an acid enters into contact with other substance, let's say, a metal... (Like in the reaction HCl(aq) + Fe(s) --> FeCl + H)

      because the term "potential of hydrogen" doesn't make sense to beginning chemistry students. It's an archaic phrase that people used to use a long time ago.

  • @anacondaeunectes1854

    • @trainingporpoises.
      @trainingporpoises. 3 года назад +1

      Does it really make you understand more if someone tells you it stands for "potential of hydrogen?" that is the real jargon and that isn't going to make any sense to anyone. Watch the whole video, it tells you everything you need to know.
