Colloids
- A colloid is a kind of solution in which the size of solute particles is intermediate between those in true solutions and those in suspensions.
- For Example: - Soap solution, Milk, Ink, Blood and solutions of synthetic detergents.
- In a true solution, the solute particles are so small that they cannot scatter or reflect light rays falling on them.
- In a colloidal solution (or colloid), the particles are big enough to scatter light.
- If a beam of light is put on a colloidal solution kept in a beaker in a dark room, the path of light beam is illuminated and becomes visible when seen from the side.
- The path of light beam becomes visible because colloidal particles are big enough to scatter light falling on them in all directions.
