Answers
Answer:
a.Sodium chloride from its solution in water can be separated by Evaporation.
b. Ammonium chloride from a mixture containing sodium chloride and ammonium chloride can be separated by Sublimation.
c. Filtration: Small metal pieces can be filtered by using a Suitable Filter.
d. Different pigments from an extract of flower petals : Chromatography.
e. Butter from curd can be separated by centrifugal machine or churning the curd by hand.
f. Decantation: By using separating funnel, Oil and water form separate layers which are separated by using separating funnel.
g. Tea leaves from tea: Filtration
h. Iron pins are separated from sand by the process of Magnetic Separation.
i. Wheat grains from husk : Winnowing.
j. Coagulation and decantation: Alum is added to the muddy water which makes the soil particles heavier so they settle down. The clear water is then separated by decantation.
