Question

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

• A. In both, particles can be seen through the naked eye.
• B. In both, particles cannot be seen through the naked eye.
• C. Both can scatter light and make its path visible.
• D. Both can be separated by filtration.

Answer 1

The correct option is C

Both can scatter light and make its path visible.

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. Unlike colloids, the constituents of the suspension can be separated by using a filter paper.
