Question

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: (A) Both (A) and (R) are correct and (R) is the correct explanation of (A) (B) Both (A) and (R) are correct but (R) is not the correct explanation of (A) (C) (A) is correct but (R) is not correct (D) (A) is not correct but (R) is correct

Answer: C) (A) IS CORRECT BUT (R) IS NOT CORRECT

💡 Solution & Explanation

Parchment paper is a semi-permeable membrane which allows particles of true solution to pass through as their size is too small. Hence, the assertion is correct but the reason is incorrect.
