Question

Assertion: An ordinary filter paper impregnated with collodion solution stops the flow of colloidal particles.

Reason: Pore size of the filter paper becomes more than the size of colloidal particle.

Options

  • Assertion and reason both are correct and the reason is correct explanation of assertion.

  • Assertion and reason both are correct but reason does not explain assertion.

  • Assertion is correct but reason is incorrect.

  • Both assertion and reason are incorrect.

  • Assertion is incorrect but reason is correct.

MCQ

Solution

Assertion is correct but reason is incorrect.

Explanation:

Colloidal particles can pass through ordinary filter paper because the pores are too large. However, the pores of filter paper can be reduced in size by impregnating with collodion solution to stop the flow of colloidal particles.
