Question

The movement of colloidal particles under the influence of an electric field is called ______.

Answer 1

The movement of colloidal particles under the influence of an electric field is called electrophoresis.

Explanation:

Electrophoresis occurs because colloidal particles carry a particular type of charge, causing them to move toward the electrode of the opposite charge when an electric field is applied. This movement demonstrates the charged nature of colloidal particles and has important industrial applications.
