What is the order of diameter of colloidal particles? |
10-3 m 10-6 m 10-15 m 10-7 m |
10-7 m |
Colloidal state of matter is, therefore, a state in which the size of the particles is such (1 to 1000 nm) that they can pass through filter paper but not through animal or vegetable membrane. By using the proper techniques, any material may be converted into a colloidal form. |
