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?
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.
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.]
