Activity 2.6 Class 9 Science
· Let us try to separate kerosene oil from water using a
separating funnel.
· Pour the mixture of kerosene oil and water into a separating funnel.
· Let it stand undisturbed for some time so that
separate layers of oil and water are formed.
· Open the stopcock of the separating funnel and pour
out the lower layer of water carefully.
· Close the stopcock of the separating funnel as the oil
reaches the stop cock.

Observation Activity 2.6 Class 9 Science
We
observe two separate layers of kerosene oil and water. They are insoluble to
each other. Kerosene oil is lighter than water so it forms the upper layer and
water forms the lower layer.
Conclusion Activity 2.6 Class 9 Science
Immiscible
liquids separate out into different layers because of differences in their
densities so they can be separated using a separating funnel.
Immiscible
liquids – A mixture of two or more liquids that do not mix with each other.
These liquids have differences in their densities.
Applications of Activity 2.6 Class 9 Science
i. This method is used in the extraction of organic compounds present in an aqueous solution.
ii. During extraction of iron, this method is used to separate out molten slag and molten iron in the blast furnace.
iii. To separate the mixtures of water and benzene, carbon tetra chloride, and water.
