Electroloids are colloidal dispersions of particles that exhibit electrical charge, allowing them to interact with electric fields. These particles can be either positively or negatively charged and are typically suspended in a medium, often water. The electrical properties of electroloids enable them to stabilize against sedimentation and can influence various applications, such as in electrochemistry, food science, and pharmaceuticals. Their behavior is crucial in processes like electrophoresis and electrocoagulation.
