Chromatography is a laboratory technique for the separation of a mixture. The mixture is dissolved in a fluid called the mobile phase‚ which carries it through a structure holding another material called the stationary phase. The various constituents of the mixture travel at different speeds‚ causing them to separate. The separation is based on differential partitioning between the mobile and stationary phases. Subtle differences in a compound’s partition coefficient result in differential retention

Separation Of A Dye Mixture Using Chromatography ********* AP Chemistry (3rd Block) Fauquier High School 8/ 31/ 13 ABSTRACT: The Rf values of seven known color dyes and three unknown samples were observed in order to compare results and discover the hidden identities of the three samples. Three solvents‚ H2O‚ Isopropyl alcohol‚ and a 2% NaCl solution‚ were introduced to the dotted chromatography strips to show three different ratios for each dye on

Purpose 1. To prepare a dry-packed sample of product mixture of ferrocene and Acetylferrocene 2. To separate and purify the components in the product mixture by column chromatography. 3. To check the purity of the components by thin-layer chromatography (TLC). 4. To calculate the yield of acetylferrocene and the percent recovery of unreacted ferrocene.

Lab 5 Oxidation of an alcohol CHM2123 Introduction: Oxidation is a key reaction in organic chemistry. Oxidation of an alcohol can produce aldehydes‚ ketones‚ or carboxylic acids. One of the methods of oxidation is an aldol reaction through carbon-carbon bonds. The oxidation oxidizes primary alcohols to aldehydes and secondary alcohols oxidizes ketones. Tertiary alcohols are converted to the common oxidizing agents. Scheme 5.1: Aldehydes can be oxidized easily to carboxylic acids in aqueous medias

MIXTURES‚ SOLUTIONS‚ SUSPENSIONS AND COLLOIDS MIXTURES A mixture is a combination made up of two or more different substances which are mixed but are not chemically bonded. There are also types of mixtures such as homogeneous mixtures and heterogeneous mixtures. SOLUTIONS A solution is defined as a homogeneous mixture composed of a solute; a substance dissolved into another substance known as a solvent. They can also be defined as groups of molecules that are mixed up completely in even

Candy chromatography My experiment is called candy chromatography. This project is mainly about the colors that are mixed with other colors to make candy markers Koolaid and much more. I think that only the color of the candy is going to show up on the coffee paper. I think that threw the entire experiment the color in the candy is going to show up the entire time. I think this is going to happen because most of the colors are solid colors. The material and equipment used was a sample of candy

Blood Gas Analysis at the Core Laboratory at University Hospital‚ London‚ Ontario. Blood is one of the most important fluids in the human body. It helps carry nutrients such as oxygen to the cells in the body and transports out wastes like carbon dioxide and other metabolites from these cells. Since blood is the medium through which the different organs and tissues in our body communicates‚ keeping a close eye on the constituents of a blood sample would provide a good indication of the functioning
