Separation techniques followed: Sublimation, filtration and evaporation.
 
Procedure:
 
Step 1
 
1. Take 3 spatulas of the given mixture in a china dish.
 
2. Cover the china dish using by placing a funnel as shown in the picture.

Step 2
 
1. Cool the left over mixture from the first experiment.
 
2. Add 10ml of water to it and stir well.
 
3. Filter the solution using a funnel and filter paper. Collect the filtrate in a test tube.
 
4. Boil the filtrate in the test tube to remove water completely (Note: Stop heating the moment you see a white deposit at the side of the test tube)
 
5. Write also a concluding report on the experiment.
 
Precautions:
 
1. China dish and funnel should be clean and dry.
 
2. Start heating slowly and then make it strong.
 
3. Cool the china dish before adding water to it, other wise it may break.
 
Report:
 
1. After heating we observed that Ammonium chloride gets separated as its sublimate, which is deposited in the funnel.
 
2. After boiling off water completely from the filtrate we observed that a white solid of sodium chloride get separated.
 
Questions:
 
1.How do you separate dissolved sugar from a solution of sugar in water?
 
2.What is filtration used for?
 
3.Suggest some methods of purification with examples.
 
4.What happens when NH4Cl is heated in an open container? (NH4Cl(s)  HCl(g) + NH3(g))
 
5.What happens when NH4Cl is heated in a closed container? (HCl + NH3  NH4Cl(s); This process is called sublimation
 
6.What is a sublimate? (The product obtained after the sublimation process is called a sublimate.)
 
7.When do we employ the technique of filtration to separate a component from a mixture?
 
(One should dissolve in a suitable solvent)
 
8.When do we employ the technique of boiling/evaporation to separate a component from a mixture?
 
 
(The substance dissolved does not undergo decomposition or evaporation)
