Answer 2

When an electric current is passed through the colloidal solution, it is called Electrophoresis.

• When an electric current is passed through the colloidal solution, the colloidal particles move freely with regard to the charged plates.
• Electrophoresis occurs due to the charge possessed by the colloidal particles.
• The electrons move freely due to the electric field provided by the electric current.

Hence, Electrophoresis takes place when the electric current is passed through a colloidal solution.
