Which separation techniques will you apply for the separation of the following?
$(a)$ Sodium chloride from its solution in water.
$(b)$ Ammonium chloride from a mixture containing sodium chloride and ammonium chloride.
$(c)$ Small pieces of metal in the engine oil of a car.
$(d)$ Different pigments from an extract of flower petals.
$(e)$ Butter from curd.

$(c)$ Small pieces of metal in the engine oil of a car.
$(d)$ Different pigments from an extract of flower petals.
$(e)$ Butter from curd.
(N/A) Evaporation: The solution is heated until the water evaporates,leaving behind solid sodium chloride.
$(b)$ Sublimation: Ammonium chloride sublimes on heating,while sodium chloride does not,allowing for separation.
$(c)$ Filtration: Metal pieces are solid particles that can be separated from the liquid oil using a filter.
$(d)$ Chromatography: This technique is used to separate different pigments based on their differential solubility in a solvent.
$(e)$ Centrifugation: Butter is separated from curd by spinning it at high speeds,which forces the denser components to the bottom and lighter butter to the top.
