Chemistry

The right option for the statement “Tyndall effect is exhibited by”, is:
(1) $\mathrm{NaCl}$ solution
(2) Glucose solution
(3) Starch solution
(4) Urea solution

Answer is (3)

Tyndall effect is exhibited by colloidal solution only.

Among the given options, Urea, $\mathrm{NaCl}$ and Glucose solutions are true solutions, so cannot show Tyndall effect.

Starch solution is a colloidal solution therefore can show Tyndall effect.
