Separation of Substances
Chapter: 6
| PART – I |
| IMPORTANT QUESTION ANSWER |
A. Answer the following Question:
(i) What is the main purpose of separating substances from a mixture?
Ans: To remove non-useful components, obtain useful products, and get pure materials.
(ii) What is the principle of filtration?
Ans: Separating insoluble solids from liquids using a filter.
(iii) What is the difference between homogeneous and heterogeneous mixtures?
Ans: A homogeneous mixture has a uniform composition throughout, e.g., salt dissolved in water.A heterogeneous mixture has a non-uniform composition, e.g., sand and water.
(iv) What is sedimentation? Give an example.
Ans:Sedimentation is the process where heavier insoluble particles settle at the bottom of a liquid.
Example: Mud particles settling at the bottom of a container filled with muddy water.
(v) What are the conditions required for magnetic separation?
Ans: Magnetic separation requires one of the components to be magnetic (like iron) while the other should be non-magnetic (like sand), allowing the magnet to attract and separate the magnetic substance.
(vi) What is the method used to separate grains from stalks in agriculture?
Ans: The method used to separate grains from stalks is threshing. This is done by beating the stalks to release the grains.
(vii) How is magnetic separation used in daily life?
Ans: Magnetic separation is used to remove magnetic materials like iron filings from non-magnetic substances, such as when separating iron filings from sand.
B. True or False:
1. Churning is used to separate cream from butter.
Ans: False. (Churning separates cream from milk to make butter.)
2. Sieving is used to separate substances based on their solubility.
Ans: False. (Sieving separates substances based on their size, not solubility.)
3. Magnetic separation is effective when both components are magnetic.
Ans: False. (Magnetic separation works only when one component is magnetic and the other is not.)
4. Winnowing is used to separate heavy particles from lighter ones using wind.
Ans: True.
5. Filtration can be used to separate soluble substances from liquids.
Ans: False. (Filtration is used to separate insoluble solids from liquids.)
