Question

The right option for the statement “Tyndall effect is exhibited by”, is:

Options

• Urea solution

• NaCl solution

• Glucose solution

• Starch solution

Answer 1

Starch solution

Explanation:

The Tyndall effect is exhibited by colloidal solutions, where light is scattered by particles of colloidal size. Starch solution is colloidal and hence shows the Tyndall effect, whereas urea, NaCl, and glucose solutions are true solutions that do not scatter light appreciably. Thus, starch solution exhibits the Tyndall effect.
