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.

Background Information and Research Paper chromatography uses selective adsorption on a strip of paper. It is used for separating and identifying mixtures that are or can be colored‚ especially pigments. This can also be used in secondary or primary colors in ink experiments. Is it used for Contaminants in rainwater‚ Analysis of narcotics‚ and Detection of substances in urine. Purpose • The purpose of this lab is to see the separation of dye on the candy.

Alkenes from Alcohols: Analysis of a Mixture by Gas Chromatography Aim: To analyze a mixture of alkenes by gas chromatography. Introduction: In this lab‚ we specifically used elimination reaction; however we only used the E1 reaction. In the presence of strong acids‚ alcohols protonate to form a good leaving group‚ namely water. Upon loss of a proton to a good leaving group‚ an introduction of unsaturation (a double bond) can be preformed. According to Wikipedia‚ an E2 reaction is typically
