Solution:
Given Mixture – Sand + Iron filings + Ammonium chloride +Sodium chloride
Iron filing can be separated by using magnet which will attract all the iron filings.
Now by the process of sublimation we can separate ammonium chloride from the mixture as it is the only constituent which get sublimate.
Now we mix the remaining salt and sand in water. The sodium chloride will dissolve in water and we can collect the sand which will settle in the base.
Now we are left with salt solution. By the process of evaporation water will vaporise and we are left with salt .
