Question

A suspension and a colloidal solution, both are heterogeneous mixtures. Identify the correct statement(s) referring to both types of solutions.

• A. In a suspension, the particles cannot be seen with the naked eye whereas, in a colloidal solution, they can be.
• B. In a 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 a 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.

A suspension is prepared by dissolving solid particles into the 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.
