Question

Identify the correct statement(s) referring to both types of heterogeneous mixtures.

• A. In a suspension, the particles cannot be seen with the naked eye whereas in a colloidal solution, they can be.
• B. In suspension, the particles can be seen with naked eye whereas in a colloidal solution, they cannot be.
• C. Both can scatter light and make its path visible.
• D. Only suspension can scatter light and colloidal solutions cannot.

Answer 1

Answer: (B), (C)

The correct options are
B In suspension, the particles can be seen with naked eye whereas in a colloidal solution, they cannot be.
C Both can scatter light and make its path visible.

Suspension is prepared by mixing solid particles of sufficiently larger size into liquid. The solid particles in such solutions do not dissolve and are visible to the naked eye. They scatter a beam of light passing through it and make its path visible. A colloidal solution also shows such light scattering phenomenon except that the particles are relatively smaller in size.
