  • This video shows how you can calculate the Ka of an acid, if you're given the pH of the solution (and its concentration, of course). It's pretty straightforward if you understand where the Ka expression comes from (Equilibrium).

    I have no idea why teachers make chemistry soooo complicated.. you just make it so clear. thank you so much. looking forward to my exams next week.i love your videos you are so funny.one love man.

    I've been near the edge of pulling my hair out of how the hell you get the values for the equation.so if they give you a pH the value is substituted for the exponent that's with given [H+] value. then you plug it in.....alright that's It. I'm coming to you more now.

  • @VincenzoCrawford
    @VincenzoCrawford 10 ปีที่แล้ว +1

    the video was great in identifying how to calculate the Ka ... however the stoichiometric is not complete. a compound cannot "by itself dissociate" ... therefore the real equation should be [ HClO + H2O H3O+ + ClO- ] ... even tho H2O will be ignored and not be calculated into the equation as its value would be 1 (because H2O can be a base as well as an acid)
    this vid still helped me tho ... #respect

    • @aban33
      @aban33 9 ปีที่แล้ว +1

      This is because there is no amount of either of them present in the solution INITIALLY.
      Imagine you have an empty beaker. It is then filled halfway with water. The very INSTANT you pour in an acid (let's say HCl), the only thing present in the solution is HCl and H2O. This is because INITIALLY the HCl has not had a chance to ionize (dissociation). The reaction must proceed forward in order for there to be H+ and Cl- ions in the water in order for there to be values in the ICE table, which is why there is a +X CHANGE in the ICE Table and a value available after the solution (and reaction) has reached equilibrium.
      I hope this helped! Good luck!
