Question

Assertion: Dissolved substances can be removed from a colloidal solution by diffusion through parchment paper.

Reason: Particles in a true solution cannot pass through parchment paper but the colloidal particles can pass through the parchment paper.

Options

• If both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.

• If both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.

• If Assertion is correct but Reason is incorrect.

• If Assertion is incorrect but Reason is correct.

Answer 1

If Assertion is correct but Reason is incorrect.

Explanation:

Dissolved substances (true solution particles) can pass through parchment paper by diffusion, so the assertion that dissolved substances can be removed from a colloidal solution by diffusion through parchment paper is correct. However, the reason is incorrect because colloidal particles cannot pass through parchment paper, whereas true solution particles can. Therefore, the assertion is correct but the reason is incorrect.
