    I am a french student and this video was extremely helpful... Thanks to you, I am now able to understand the notion of pKa ! ;)

    great video thanks
    at 6:15 (conjugate base not acid)

    Thank you so much! I was struggling because I couldn't understand the difference between Ka and pKa.

    Where was he during my biochem nightmare of a class???
    :(
    I finally truly understood pKa.
    Thank you!!!

    pure water is NOT neutral despite common misconception. Ions dissolved in water create solvation spheres around them and effectively lower the conc. of H+. pure water is infact acidic

    In 6:13 you're saying A- is a conjugate acid. Shouldn't it be a conjugate base instead?

    Is pka particular to a substance OR to a substance in a certain reaction/solution?

    Sir, 8:23 large ka means higher acidic and lower ka means weak acid and then in list of compounds low pka turn higher acidic vice versa whyyyyyyy😭😭😭😭😭

    • @shreyas4858
      @shreyas4858 3 роки тому

      it's the opposite, larger the Ka, less acidic is the substance

    • @gracer1486
      @gracer1486 3 роки тому +1

      They are inversely related because of the -log

      @@shreyas4858 Large Ka means MORE acidic, but large pKa means LESS acidic.
      Large Ka means that the concentration of products (hydronium and conjugate base) is much greater than concentration of reactants. This means that a lot of the reactants stayed dissociated and that the products are favored. Therefore, it means that the molecule is more acidic than a molecule with a lower Ka.
      To get pKa, you have to take the negative log of Ka. Therefore, high Ka meas low pKa. Since high Ka means high concentration of dissociated products, low pKa means more acidic. Conversely, high pKa means the molecule has a low Ka, telling us that the reactants were favored. Therefore, high pKa means that the molecule doesnt dissociate as easily

  • @pratibhagupta8816
    @pratibhagupta8816 3 роки тому +1

    If there is already a pH scale to define how strong the compound is acidic or basic then why they introduced pka value 😵😵🤕🥺
    Is there any other use??
    Anyways sir you explain very great 😁😁

      pKa is more specific in that it helps you predict what a molecule will do at a specific pH. Essentially, pKa tells you what the pH needs to be in order for a chemical species to donate or accept a proton.
