Question

Describe briefly the following:

Electrophoresis

Describe the following term while stating the property of colloid:

Electrophoresis

Answer 1

Electrophoresis is the movement of colloidal particles towards a specific electrode under the influence of an electric field. This movement occurs because colloidal particles carry an electric charge, either positive or negative. When subjected to an electric field, particles with a positive charge migrate towards the cathode, while negatively charged particles move towards the anode. The direction of migration depends on the type of charge present on the particles. Electrophoresis is a significant phenomenon as it confirms the charged nature of colloidal particles and has various practical applications in industries, such as purification and sewage treatment. Its study helps in understanding the stability and behavior of colloidal solutions under electric fields.
