You are provided with a mixture containing sand, iron fillings, ammonium chloride and sodium chloride. Describe the procedures you would use to separate these constituents from the mixture?

AcademicChemistryNCERTClass 9

To separate these constituents from the mixture, the following steps should be followed-
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.

[Extra information:
Magnetic separation: It is the process of separating components of mixtures by using a magnet to attract magnetic substances from the mixture.
Sublimation: It is the transition of a substance directly from the solid to the gas state, without passing through the liquid state.
Filtration: It is a physical separation process that separates solid matter and fluid from a mixture using a filter medium.]
