Question

Which separation techniques will you apply separation of the following:

1)Sodium chloride from its solution in water.

2)Ammonium chloride from a mixture containing sodium chloride and onium chloride.

3)Mixture of oil and water.

4)Fine mud particles suspended in water.

Answer 1

Solution:-

• Sodium chloride from its solution in water-
  

Evaporation $\to$ Water will evaporate leaving behind sodium chloride.

• Ammonium chloride from a mixture containing sodium chloride and ammonium chloride-
  

Sublimation $\to$ Ammonium chloride will be collected as sublime

• Mixture of oil and water-
  

Using separating funnel $\to$ Oil and water can be separated by the use of separating funnel.

• Fine mud particles suspended in water-
  

Sedimentation $\to$ As a result of sedimentation, mud particles will settle as a precipitate. It can be separated latr on by filteration
