Question

Which separation technique will you apply to separate the following mixture.

a) Ammonium chloride from a mixture of sodium chloride and ammonium

chloride.

b) Butter from curd

c) Small pieces of metal in the engine oil of a car

d) Oil from water​

Answer 1

Answer:

a) Sublimation

b) Centrifugation

c) Magnetic Separation

d) By Separating Funnel

Answer 2

Answer:

Ammonium chloride is separated from a mixture of sodium chloride and ammonium chloride by the process of sublimation. Ammonium chloride can be sublimed whereas sodium chloride cannot be sublimed. When a mixture of sodium chloride and ammonium chloride is heated, ammonium chloride changes its state from solid to vapour.

Butter can be separated from curd by the process of Centrifugation. The principle behind this process is that the denser particles are forced to the bottom and the lighter particles stay at the top when spun rapidly.

Small pieces of metal in the engine oil of a car – vacuum filtration. This is because vacuum filtration is performed under pressure, so it will be able to separate the dense oil from the metal pieces.

Two immiscible liquids, oil and water, can be separated by using Separating Funnel. The process involves using the mixtures of unequal particle density. Because water is denser than oil, it can be separated by means of the funnel and left in the funnel with an oil layer.
