Explain the phenomenon observed An eleetrlc current is passed through a colloidal solution. |
Answer» Electrophoresis : The existence of charge on colloidal particles is confirmed by electrophoresis experiment. When electric potential is applied across two platinum electrodes dipping in a colloids solution, the colloidal particles move towards one or the other electrode. The movement of colloidal particles under an applied emf is called "electrophoresis". `to` Positive charged particles move towards the cathode while negative charged particies towards anode. |
