Which of the following statements is true regarding electrophoresis of colloids?
Positively charged colloids move towards the cathode
Negatively charged colloids move towards the anode
Neutral colloids do not move under the influence of an electric field
Colloids move towards the opposite electrode of their charge
Correct Option 4) Colloids move towards the opposite electrode of their charge
Electrophoresis is a method used to separate and analyze colloidal particles based on their charge and size. When an electric field is applied to a colloidal solution, the charged particles move towards the electrode of the opposite charge. The direction of movement depends on the charge of the particles.
Positively charged colloids move towards the cathode, while negatively charged colloids move towards the anode. Neutral colloids do not have a charge and do not move under the influence of an electric field.
