- What kind of mixture of substance has Distillation and Chromatography has?Consider four distinct physical properties: boiling point, melting point, solubility, and density. Which of these physical properties do you think allows thin layer chromatography (TLC) to work? Choose one then, explain your reasoning.In three sentences, describe the principle of chromatography.
- 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 of the following is paper chromatography NOT useful for? a) Determine the identity of a component in a mixture b) Determing the number of components in a mixture c) Determining the amount of each component in a mixture d) Determining the polarity of compoundsChemistry Consider the following chromatogram. The early eluting peaks and later eluting peaks exhibit a problem. Propose a way in gas chromatography to eliminate both problems.
