Solubility as a Property of Matter A Lab of Chemicals‚ Chromatography‚ and Crime! Chemistry is a natural science that deals with the composition of matter and the changes it undergoes. At crime scenes‚ investigators often find unknown materials that need to be identified. If an unknown material is a mixture‚ an investigator may want to know one or two things about it: What are the ingredients of the mixture? Is the mixture found at the scene the same as a known mixture? A mixture is a collection

caused the ink to move the least. (5 points) 4. What differences did you observe in how the different colored inks were separated? Answer: They were separated by each color of ink and how they were mixed together. Then when you use paper chromatography you’ll see all the different pigments of that separation. (5 points) 5. What observations would lead you to believe that the ink is actually a mixture? Answer: It’s a mixture because you have to originally mix things to get the ink color.
