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 tea.
(g) Tea leaves from tea.
(h) Iron pins from sand.
(i) Wheat grains from husk.
(j) Fine mud particles suspended in water.

Explanation

Various separation techniques can be used based upon the type of the mixtures.
a) Sodium chloride from its solution in water can be separated by using the evaporation process.
b) Ammonium chloride from a mixture containing sodium chloride and ammonium chloride can be separated by using the sublimation process.
c ) Small pieces of metal in the engine oil of a car can be separated by using the filtration process.
d) Different pigments from an extract of flower petals can be separated by chromatography technique.
e ) Butter can be isolated from curd b using centrifugation technique.
f) Oil from water or tea can be separated by using a separation funnel.
g) Tea leaves from tea can be separated by using filtration process.
h) Iron pins from sand can be separated by using magnetic separation.
i) Wheat grains from husk can be separated by using the winnowing technique.
j) Fine mud particles suspended in water can be removed or separated by using sedimentation followed by using the filtration method.
