Question

draw a scheme for separating mixture containing iron filings, sulphur powder, sand common salt please guys help me ​

Answer 1

Hey mate,

Step-1: Separate iron filings with the help of a magnet.

Step-2: Sublimation of the remaining mixture separates ammonium chloride when solid directly converts to gaseous vapors.

Step-3: Add water to the remaining mixture, stir and filter out sand by filtration.

Step-4: The filtrate can be evaporated to get back sodium chloride.

Hope it helps.

Answer 2

Explanation:

Solution. The method for separating a mixture of iron filings and sulphur powder, employs the use of carbon disulphide as a solvent followed by filtration and evaporation. Sulphur dissolves in carbon disulphide, whereas iron does not. So, the solution will contain undissolved iron in it.

Iron is magnetic and the other two not, which means a magnet could be used to attract the iron filings out of the mixture, leaving the salt and sand. Salt is water soluble, while sand is not. This means the two can be mixed in water and stirred. The salt will dissolve and the sand will not.
