JEE PYQ: Surface Chemistry Question 1
Question 1 - 2021 (16 Mar Shift 2)
Type: MCQ
The INCORRECT statements below regarding colloidal solutions is:
(1) A colloidal solution shows colligative properties.
(2) An ordinary filter paper can stop the flow of colloidal particles.
(3) The flocculating power of $\text{Al}^{3+}$ is more than that of $\text{Na}^+$.
(4) A colloidal solution shows Brownian motion of colloidal particles.
(a) A colloidal solution shows colligative properties.
(b) An ordinary filter paper can stop the flow of colloidal particles.
(c) The flocculating power of $\text{Al}^{3+}$ is more than that of $\text{Na}^+$.
(d) A colloidal solution shows Brownian motion of colloidal particles.
Show Answer
Answer: (a)
Solution
Colloidal solution exhibits colligative properties. An ordinary filter cannot stop the flow of colloidal particles. Flocculating power increases with increase in the opposite charge of electrolyte. Colloidal particles show Brownian motion.
