- use ion exchange method in analytical separation to separate mercury and nickel from polluted water using analytical steps and protocols.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…Which one is the most common method used for the purification of liquid mixtures? Filtration Chromatography Evaporation Distillation
