Answer 2

In solutions, the particles are invisible.

• A solution is a homogenous solution where the solute particles are completely mixed within the solution.
• The particles are less than 1 nm and do not collect on filter paper or animal membrane, hence are not visible to the naked eye or ordinary microscope.
• The sheet appears white and hence the particles are not even visible with the ultramicroscope.
• Particles of a suspension can be visualized by an ordinary microscope or even seen by naked eyes as they settle at the bottom.
• Colloidal particles sizes range from 1 nm to 1000 nanometer. They do not settle and appear as translucent. Therefore, they are not visible by an ordinary microscope But the phenomenon is shown by them - the scattering of light or Tyndall effect is visible under an ultramicroscope.
