Question

1. Which separation technique was used for the separation of the given mixture?
sublimation
2. Why was this technique used? becoce
3. Why can't we use filtration technique for separation of this mixture?
4. Name two more substances which undergo sublimation
5. Suggest a sequence of separation technique you will use for separation of a
mixture of camphor, common salt and sand.
6. Label the diagram given below.​

Answer 1

Answer:

1.Sublimation is a technique used to separate the components of a mixture containing a sublimable volatile solid and a non-sublimable impurity. Therefore, the mixture of camphor and sodium chloride can be separated by the process of sublimation.

2.The 5 Whys technique is a simple and effective tool for solving problems. Its primary goal is to find the exact reason that causes a given problem by asking a sequence of “Why” questions. ... It gives your team the confidence that it can eliminate any problem and prevent the process from recurring failures.

3.Insoluble particles can be separated from a mixture using filter paper in a funnel as shown below. The particles of solutes dissolved in a solution are so small that they can't be seen, and they can't be separated from a solution by filtration.

4.Camphor, maphthalene, ammonium chloride, iodine, and dry ice are some substances which undergo sublimation.

5.camphor can be separated using sublimation as it is a sublime,common salt and sand mixture can be separated using evaporation and filtration respectively.
