Match List I with List II and select the correct answer using the code given below the Lists:

LIST I (Process)		LIST II (Separation method)
A.	Separation of acetone and water from their mixture	1.	Chromatography
B.	Separation of water and kerosene oil from their mixture	2.	Centrifugation
C.	Separation of cream from milk	3.	Distillation
D.	Separation of pigments from plant extract	4.	Separating Funnel

The correct answer is A - 3, B - 4, C - 2, D - 1.

Key Points

• Separating acetone and water from their mixture:
  • Distillation is a process that involves heating a liquid mixture to form a vapor and then cooling that vapor to form a liquid.
  • It is particularly useful for separating components with different boiling points.
  • In this case, acetone and water have different boiling points, allowing them to be separated through distillation.
• Separation of water and kerosene from their mixture:
  • A separating funnel is used to separate immiscible liquids (liquids that do not dissolve in each other).
  • In the case of water and kerosene, which do not mix well, a separating funnel may be used to allow the two liquids to be separated based on their different densities.
• Separation of cream from milk:
  • Centrifugation involves spinning a mixture at high speed, causing the components to separate based on their density.
  • In the case of cream and milk, centrifugation can be used to separate the denser cream from the less dense milk.
• Isolating pigments from plant extracts:
  • Chromatography is a technique that separates components for stationary phase and mobile phase based on their different affinities.
  • In the case of pigments from plant extracts, chromatography can be used to separate the different pigments present in the extract.
