Question

Which among the following mixtures will show tyndal effect?

i) copper sulphate solution
ii) sand in water.
iii) milk.
iv) starch solution ​

Answer 1

milk and starch solution

Step-by-step explanation:

Tyndall effect is shown by colloidal solutions. It is not shown by true solutions or suspensions.

Milk and starch solution are colloidal solutions. They show tyndall effect. On the other hand, common salt and copper sulphate solution are true solutions. They do not show tyndall effect.

Answer 2

milk and starch solution are the colloids, hence these will show the tyndall effect
