Question
State whether the following statements are true or false.
STATEMENT-1:
STATEMENT-2:
STATEMENT-3:
(i) The particles of suspension scatter a beam of light passing through them and making their path visible.
(ii) In the solution, a particle of solute can be separated from the mixture by filtration.
(iii) A solution in which the solute concentration is much less than that of the solvent is called a dilute solution.
Hint:
C
The correct answer is:
- The particles in the suspension scatter a light beam traveling through it, revealing its path. It's because of the Tyndall effect.
- Filtration cannot remove solute from a solution because solute particles dissolve in the inter-molecular gap present in water. As a result, when the solution is poured through the filter paper, the solute is likewise filtered.
- A dilute solution is one that has a small amount of solute in contrast to the solvent.
