- Discuss some applications of simple distillation and steam distillation. Explain why you can use each method for the chosen application2. The goal behind suction filtration is to remove soluble impurities that are on the surface of the crystals. Therefore, why can't you simply use suction filtration instead of recrystallization to purify an impure solid?Crystallization: What is the difference between raw and pure products?

- PAPER CROMATOGRAPHY • Define chromatography • Demonstrate an understanding of the process of chromatography • Describe the steps involved in a chromatography investigation Explanation Coloured inks are often made up of several different inks. Each colour of ink will get carried a different distance by the water, allowing you to see all of the different inks. Try this with different colours to see what actually goes into a colour. This technique is called chromatography and can be used in chemistry to find out what is in an unknown mixture. II. Materials .Felt tip pens (non-washable) . Kitchen roll .A bowl or cup . Water • Scissors III. Health and safety • Make sure that you thoroughly clean any equipment after the experiment before using for food IV. Procedure Method 1 1. Take a sheet of kitchen roll and draw a simple picture with a non-washable felt tip pen. 2. Place the sheet over an empty bowl. This is to keep the paper from getting too wet. 3. Carefully add a few drops of water…What are the functions of the graduated cylinder and distillate in a distillation set-up?2. Was there any physical change in the characteristics of trichloroethane when it was added to water?
