The migration of positively charged colloidal particles under an electrical fiel
The migration of positively charged colloidal particles under an electrical field towards the cathode is called:
- A. cataphoresis
- B. electro-osmosis
- C. sedimentation
- D. electrodialysis
Step-by-step solution
Cataphoresis refers to the migration of charged colloidal particles in an electric field. Positively charged colloids move toward the cathode (negative electrode) due to electrostatic attraction, which matches the description. Electro-osmosis involves liquid movement, sedimentation is gravity-driven settling, and electrodialysis uses membranes for ion separation.
