Given below are two statements : one is labelled as Assertion (A) and the other is labelled as Reason (R) : Assertion (A) : Dissolved substances can be removed from a colloidal solution by diffusion through a parchment paper. Reason (R) : Particles in a true solution cannot pass through parchment paper but the colloidal particles can pass through the parchment paper. In the light of the above statements, choose the correct answer from the options given below

1. Both (A) and (R) are correct and (R) is the correct explanation of (A)
2. Both (A) and (R) are correct but (R) is not the correct explanation of (A)
3. (A) is correct but (R) is not correct
4. (A) is not correct but (R) is correct

Correct answer: Both (A) and (R) are correct but (R) is not the correct explanation of (A)

Solution

Both statements are accurate; however, the reason provided does not directly explain the assertion. While it is true that dissolved substances in a true solution cannot pass through parchment paper, the assertion about removing dissolved substances from a colloidal solution is based on different principles, such as the size and nature of the particles involved.
