Current Question (ID: 18437)

Question:

$\text{Select the correct option based on statements below:}$ $\text{Assertion (A): An ordinary filter paper impregnated with collodion solution stops the flow of colloidal particles.}$ $\text{Reason (R): The pore size of the filter paper becomes larger than the size of the colloidal particle.}$

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:

$\text{Hint: The pore size of the filter paper must be smaller than the size of the colloidal particle.}$ $\text{An ordinary filter paper impregnated with a collection solution stops the flow of colloidal particles because the pore size of the filter paper becomes smaller than the size of colloidal particles.}$ $\text{Hence, Assertion is true but the reason is false.}$
