DIFFERENCE BETWEEN TRUE SOLUTIONS AND COLLOIDAL SOLUTIONS

True Solutions

Colloidal Solutions

1. The particle size is less than 10–9 cm.

2. The particles are not visible under powerful optical microscope.

3. The particles of a true solution can be recovered by evaporation and crystallization.

4. The particles of a true solution do not scatter light.

5. True solutions are clear and transparent.

6. True solutions are homogeneous in nature.

1. The particle size is in between 10-7 cm to 10-5 cm

2. The particles are visible under a microscope.

3. The particles of a colloidal solution cannot be recovered by evaporation and crystallization.

4. The particles of a colloidal solution scatter light.

5. Colloidal solutions are translucent.

6. Colloidal solutions are heterogeneous in nature.
