Answer
- Using Magnet: Move the magnet over the mixture, which will result in the sticking of iron fillings to the magnet. Like this, iron fillings get separated from the mixture.
- Sublimation: The remaining mixture is heated in a china Ammonium chloride is a sublimating substance, and it will evaporate without passing through the liquid phase. Ammonium chloride can collect an inverted funnel over china-dish.
- Sedimentation, decantation and filtration: The remaining mixture is dissolved in water and allowed to settle down. Sand will settle at the The liquid should be decanted into another beaker. Then it is filtered to remove traces of sand.
- The filtered solution is heated to evaporate the Once all the water gets evaporated, salt remains in the beaker.
