Given below are two statements:
Assertion (A): | Components of a mixture of red and blue inks can be separated by distributing the components between stationary and mobile phases in paper chromatography. |
Reason (R): | The colored components of inks migrate at different rates because paper selectively retains different components according to the difference in their partition between the two phases. |
1. | Both (A) and (R) are True and (R) is the correct explanation of (A). |
2. | Both (A) and (R) are True but (R) is not the correct explanation of (A). |
3. | (A) is True but (R) is False. |
4. | (A) is False but (R) is True. |
Statement I: | A mixture of chloroform and aniline can be separated by simple distillation. |
Statement II: | When separating aniline from a mixture of aniline and water by steam distillation aniline boils below its boiling point. |
The correct option is:
1. | Statement I is false but Statement II is true. |
2. | Both Statement I and Statement II are false. |
3. | Statement I is true but Statement II is false. |
4. | Both Statement I and Statement II are true. |
Match the type of mixture of compounds in Column I with the technique of separation/purification given in column II.
