The right option for the statement "Tyndall effect is exhibited by"
1 Glucose solution
2 Urea solution
3 Starch solution
4 \(\mathrm{NaCl}\) solution
Explanation:
Starch solution is a type of colloidal solution and other are true solution. So Starch solution shows Tyndall effect.

Assertion : Colloidal solutions do not show Brownian motion. Reason : Brownian motion is responsible for stability of sols.
1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Assertion is incorrect but reason is correct.
Explanation:
Assertion is false but reason is true. Colloidal solutions show Brownian motion and this Brownian motion is responsible for stability of sols.
