Which separation techniques will you apply for the separation of the following?

Question 1. 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.
(f) Oil from water.
(g) Tea leaves from tea.
(h) Iron pins from sand.
(i) Wheat grains from husk.
(j) Fine mud particles suspended in water.
Answer: (a) Sodium chloride from its solution in water  Evaporation.
(b) Ammonium chloride from a mixture containing sodium chloride and ammonium chloride    Sublimation.
(c) Small pieces of metal in the engine oil of a car  Filtration
(d) Different pigments from an extract of flower  Chromatography.
(e) Butter from curd  Centrifugation.
(f) Oil from water  Using separating funnel
(g) Tea leaves from tea  Filtration
(h) Iron pins from sand  Magnetic Separation
(i) Wheat grains from husk  Winnowing
(j) Fine mud particles suspended in water  Centrifugation.

      It depends on the quantity of the sand and the number of pins in it

    Cant we use crystallisation to separate sodium chloride from its solution in water?

      I guess crystallisation would take more time compared to vaporisation so evaporation is basic

      Yes. you can definitely use crystallisation, in fact, it will be better if you do. That would be because, then there would be no impurities in the salt.
