Here are some characteristics of solutions:
- The size of the particles is small
- The particles do not settle on standing
- The particles pass through ordinary filter papers
- The particles pass through permeable membranes
- The particles are not visible with microscope or the naked eyes.
- They are clear and may have a color.
