Question

which principle is involved in the following processes a) separation of ammonium chloride and common salt by using sublimation method b) separation of clay particles from muddy water by sedimentation and decantation c) separation of common salt from sea water by evaporation please answer quickly

Answer 1

Hi Friend!

Here's your answer:

a. ammonium chloride can undergo sublimation unlike common salt. So it evaporates into vapours on heating while salt is left behind in the beaker. also on cooling, solid ammonium chloride can be regained.

b.During sedimentation, clay particles settle down (due to gravity)after sometime as they are insoluble.  Decantation is the process of separating a liquid from a solid by gently pouring the liquid from the solid so as not to disturb the solid. 

c. When evaporated, water will turn into vapours and separate out from sea water solution while the salt will remain in the beaker, thus they are separated..

Hope that helps you!
