Chapter 4 - Carbon and its Compounds
Activity
4.10 Class 10 Science
· Take
about 10 ml of water each in two test tubes.
· Add a drop of oil (cooking oil) to both the test tubes and label them as A and B.
· To
test tube B, add a few drops of soap solution.
· Now
shake both the test tubes vigorously for the same period of time.
· Can
you see the oil and water layers separately in both the test tubes immediately
after you stop shaking them?
· Leave
the test tubes undisturbed for some time and observe. Does the oil layer
separate out? In which test tube does this happen first?
Discussion and Conclusions:
In test-tube B containing cooking oil, water, and soap solution was allowed to
stand after vigorous shaking for the same period of time only one layer was
observed. This shows that oil dissolves in soap and thus helps in cleaning.
On the other hand, when test tube A
containing water and cooking oil was allowed to stand after vigorous shaking,
two separate layers-one of water and the other of oil were seen.
This activity shows that oil does not dissolve in
water and hence water alone does not clean clothes. This activity also shows the
cleansing action of soap.
