Question

how will you seperate the following mixture

a) Iron nails from saw dust

b) naphthalene balls from common salt

c) cream from milk

d) oil from water

e) various dye present in black ink​

Answer 1

Answer:

a) By using magnet, iron nails can be separated from the mixture of iron nails and saw dust. This technique is known as magnetic separation

b) Sublimation is used to separate a mixture of naphthalene ball powder and common salt. Explanation: Sublimation is the process of separating naphthalene from common salt. Sublimation involves the conversion of a solid directly into vapours without undergoing the liquid state.

c)We use the process of centrifugation to separate cream from milk.

d) Two immiscible liquids, oil and water, can be separated by using Separating Funnel. The mixture of oil and water forms two separate layers because they are completely insoluble in each other. Oil forms the upper layer while water forms lower.

e)Chromatography is the technique used for separation of those solutes that dissolve in the same solvent. The ink that we use has water as the solvent and the dye is soluble in it. Hence, this method can be used to seperate dye from black ink.

Explanation:

Answer 2

Answer:

a.Iron nails are attracted by magnet. Thus, they can separated from saw dust using magnetic separation.

B.The technique of extracting naphthalene from common salt is known as sublimation. Sublimation is the process of converting a solid into vapours without going through the liquid state.

C. We use the process of centrifugation to separate cream from milk.

D.oil and water, can be separated by using Separating Funnel

E.Chromatography is the technique used for separation of those solutes that dissolve in the same solvent. The ink that we use has water as the solvent and the dye is soluble in it. Hence, this method can be used to seperate dye from black ink.
