| 5. Separation of bran & wheat flour | E: Sieving |
Question: 2. State whether the following statements are true or false. If false write –
| Statements | True/False |
| 1. Components in a mixture are present in a definite proportion. | F |
| 2. Mixtures have no definite set of properties. | T |
| 3. Components in a mixture can be separated by physical & chemical methods. | F |
| 4. Sodium chloride and water – is an example of a mixture of elements & compounds. | F |
| 5. Heterogeneous mixtures have different composition & properties throughout the mixture. | T |
Question: 3. Name the following:
Question: 1. A black non-metallic component of the mixture – gunpowder
Answer: Carbon is a black non-metallic component of the mixture gunpowder.
Question: 2. A physical method of separating iron from an iron-sulphur mixture.
Answer: Magnetic separation.
Question: 3. The component of the soluble solid-liquid mixture, which is lost to the atmosphere on heating.
Answer: Liquid component i.e. water.
Question: 4. The component of a naphthalene-sodium chloride mixture, which remains in the evaporating dish when heated together, covered with a funnel.
Answer: Sodium chloride.
Question: 5. A mixture of two immiscible liquids.
Answer: kerosene oil and water.
Question: 4. Give reasons for the following:
Question: 1. Naphthalene & camphor cannot be separated by sublimation.
Answer: Because both of these are sublimable solids and they sublimes on heating.
Question: 2. Sodium chloride cannot be separated out from its aqueous solution by filtration.
Answer: Filtration is a method that is used to separate insoluble solids from liquids, since both salt dissolve in water.
Question: 3. Two varieties of wheat flour cannot be separated by sieving.
Answer: Wheat flour particles are the same throughout on a random observation. For sieving, you require two different particle sizes like that of coarse particles and rice, etc. So, wheat varieties can’t be separated by sieving.
Question: 4. Sulphur and charcoal powder cannot be separated by magnetic separation.
Answer: Because both are non-magnetic particles.
Question: 5. Both components of a soluble solid-liquid mixture cannot be recovered by evaporation.
Answer: Because liquid is lost/evaporated in atmosphere.
