Which of the following will show Tyndall effect

Which of the following will show the “Tyndall effect”?

(a) Salt solution
(b) Milk
(c) Copper sulfate solution
(d) Starch solution.

Answer:

When a beam of light travel from a colloidal mixture. Particles of colloid scatter the light. We call this scattering of light as a Tyndall effect.

A salt and copper sulfate solution is a homogenous mixture. Milk and starch, solutions form a colloidal solution. As a result salt and copper sulfate solution does not show the Tyndall effect. While milk and starch, the solution shows a Tyndall effect.
