    This was VERY helpful. My text book was just being ridiculously complicated- sounding like it was giving me degree in Literature and not Chemistry

      Actually it’s a flexidentate ligand but mostly it’s supposed to be hexadentate but it might act as tetradentate pentadentate etc

    EDTA is HEXA not TETRA dentate :) it forms a deformed octahedric coordination mostly.

      You are correct. I think when I made this, I was thinking about biological pH, in which case the amines are protonated, but yes, if the cation (e.g., Ca++) concentration is high enough, there will be a significant amount of EDTA bound in a hexadentate manner.

    thanks man so chelation makes the complexe less chemically reactive

    • @alucardonus
      @alucardonus 5 ปีที่แล้ว

      No, chemical reactivity is the same. Its still amine. What makes complex more stable is that when you have monodentate and it gets decoordinated is simply difunds out. Bidentate, when only one donor is decoordinated cant difund too far because its chain holds it at place. Reactivity is from Thermodynamics but chelate effect is kinetics

    • @lucianaramirez8015
      @lucianaramirez8015 หลายเดือนก่อน

      Not really, it just a more beneficial reaction since its entropy driven (remember gibbs). Since there are less free molecules coordinated to a single metal, you gain overall freedom in the system as a whole

  • @zeustheboerboel3794
    @zeustheboerboel3794 7 ปีที่แล้ว

    Shouldn't the entropy decrease because less no. of ligands are getting attached? Just a silly question

    • @cameronsmith712
      @cameronsmith712 6 ปีที่แล้ว

      entropy of the complex is lowered by the process but overall entropy of the universe increases, so it is a spontaneous process

    • @DaddyDevit
      @DaddyDevit 5 ปีที่แล้ว

      Entropy is basically a measure of ‘freedom’ of a thermodynamic system. Because you have more Species floating free in the system you have more freedom so greater entropy
