    Definition :- Colloidal system or colloidal dispersion is a heterogeneous system which is made up of Dispersed phase and Dispersion medium. In colloidal dispersion one substance is dispersed as very fine particles in another substance called dispersion medium.
    Properties of a colloid
    • A colloid is a heterogeneous mixture.
    • The size of particles of a colloid is too small to be individually seen by naked eyes.
    • Colloids are big enough to scatter a beam of light passing through it and make its path visible.
    • They do not settle down when left undisturbed, that is, a colloid is quite stable.
    • They cannot be separated from the mixture by the process of filtration. But, a special technique of separation known as centrifugation can be used to separate the colloidal particles.

    Anode is always positive in charge, Anion is negative in charge people are confused between this word.

    • @anushasnigdha8213
      @anushasnigdha8213 3 ปีที่แล้ว

      This effect is used to enhance the absorption of drugs

      It is also called sedimentation potential

    In an Electrochemical cell the anode caries positive charge 🤔

  • @suraj2560
    @suraj2560 9 หลายเดือนก่อน +2

    Note: anode carries negative charge (you've written mistakenly positive charge)

    Stability se zeta potential kese related hai?

  • @shahkhan5148
    @shahkhan5148 2 ปีที่แล้ว +1

    In electrophoresis, how the electrode works? Are they work as cell or what? Then how positive charge colloids migrate towards positive? Please explain

  • @hussnainali9654
    @hussnainali9654 2 ปีที่แล้ว +8

    Anode has negative charge and cathode has positive......you explained wrong electrophoresis

    • @arsenic3673
      @arsenic3673 2 ปีที่แล้ว +6

      Nope electrophoresis me ulta hota hein

    • @suraj2560
      @suraj2560 9 หลายเดือนก่อน +1

      ​@@arsenic3673no alag books main alag hai but if you would check proper explanations then anode always has negative charge and in electrophoresis particle with positive charge goes towards the anode cause it contains negative charge (negative binds with positive)

    • @TikuDewangan-c6n
      @TikuDewangan-c6n 8 หลายเดือนก่อน +1

      During charge, the positive electrode is an anode, and the negative electrode is a cathode.10 Oct 2023
