The correct Answer is:
To solve the question, we need to analyze both the assertion (A) and the reason (R) provided: **Assertion (A):** An ordinary filter paper impregnated with collodion solution stops the flow of colloidal particles. **Reason (R):** Pore size of the filter paper becomes more than the size of colloidal particles. ### Step-by-Step Solution: 1. **Understanding the Assertion:** - An ordinary filter paper has relatively large pores compared to colloidal particles, which typically range from 1 to 1000 nanometers in size. - When the filter paper is impregnated with collodion solution, it alters the characteristics of the filter paper. - The collodion solution fills the pores of the filter paper, effectively reducing their size. - As a result, the flow of colloidal particles is stopped because they cannot pass through the now smaller pores. 2. **Evaluating the Reason:** - The reason states that the pore size of the filter paper becomes more than the size of colloidal particles. - This statement is incorrect. In fact, the impregnation with collodion reduces the pore size, making it smaller than the size of the colloidal particles. - Therefore, the reason does not correctly explain the assertion. 3. **Conclusion:** - The assertion is correct: the impregnated filter paper does stop the flow of colloidal particles. - The reason is incorrect: the pore size does not become larger than the colloidal particles; it becomes smaller. - Thus, the correct option is (c): Assertion is correct, but reason is incorrect. ### Final Answer: (c) Assertion is correct, but reason is incorrect.
To solve the question, we need to analyze both the assertion (A) and the reason (R) provided: **Assertion (A):** An ordinary filter paper impregnated with collodion solution stops the flow of colloidal particles. **Reason (R):** Pore size of the filter paper becomes more than the size of colloidal particles. ### Step-by-Step Solution: ...
