Question

name the property of one of the constituent which can be used to separate a mixture of (1) Iron filling and sulphur (2);sodium chloride and camphor (3) sulphur and carbon (4) common Salt dissolved in water​

Answer 1

Answer:

Hope this helps you

Explanation:

1. Iron filling- It is magnetic so it can be separated from sulphur by magnetic Seperation.

2 Camphor - They are big in size compared to sodium chloride. Seperation process Handpicking.

3.Water - Water can evaporate So the process involved is Evaporation

Pls mark as brainliest if the ans is help full.

Answer 2

1) Magnet

2)sublimation

3)carbon disulphide solution

4)evopration

Explanation:

1)A mixture of iron filling and sulphur powder can be separated by using a magnet. This is because iron filling are attracted by magnet whereas sulphur is not attracted by a magnet.

2)Sublimation: Mixture of camphor and sodium chloride is heated in a china dish covered with an inverted funnel closed from the lower end. Camphor sublimes and collects on the inner wall of the funnel. ... Residue left on filter paper is camphor.

3)The mixture of carbon and sulphur can be separated from each other by using a solution of carbon disulphide. Sulphur gets dissolved in the solution whereas carbon remains undissolved. This mixture is then filtered to remove carbon followed by evaporation to obtain sulphur.

4)We can recover common salt from salt water mixture by the process of evaporation. The solution of common salt and water is taken in a porcelain dish and heated gently by using a burner. The water present in salt solution will form water vapours and escape into atmosphere.
