Current Question (ID: 18421)

Question:

$\text{Select the correct option based on statements below:}$ $\text{Assertion (A): Colloidal solutions do not show Brownian motion.}$ $\text{Reason (R): Brownian motion is responsible for the stability of sols.}$

Options:

1. $\text{Both (A) and (R) are true and (R) is the correct explanation of (A).}$
2. $\text{Both (A) and (R) are true but (R) is not the correct explanation of (A).}$
3. $\text{(A) is true but (R) is false.}$
4. $\text{(A) is false but (R) is true.}$

Solution:

$\text{Hint: Brownian movement is a property of the colloidal solution.}$ $\text{Explanation:}$ $\text{When colloidal solutions are viewed under a powerful ultramicroscope, the}$ $\text{colloidal particles appear to be in a state of continuous zig-zag motion all}$ $\text{over the field of view. This movement is known as the Brownian movement.}$ $\text{The Brownian movement has a stirring effect which does not permit the}$ $\text{particles to settle and thus, is responsible for the stability of sols.}$ $\text{So, option 4 is the correct answer.}$
