5.5 Candy Chromatography Background Information: Paper Chromatography is a separation tool in which pigment is put on a paper made of cellulose and water‚ and placed in a solvent‚ in this case isopropyl alcohol. Due to capillary action‚ the solvent crawls up the paper‚ separating the pigments. This technique is used to identify components of a mixture‚ even unknown ones‚ and can be used to isolate components into pure samples. Real world uses of this technique includes identifying certain biomolecules

Sustainable Chemistry Terry Collins* Chemistry has an important role to play in achieving a sustainable civilization on Earth. The present economy remains utterly dependent on a massive inward flow of natural resources that includes vast amounts of nonrenewables. This is followed by a reverse flow of economically spent matter back to the ecosphere. Chemical sustainability problems are determined largely by these economy-ecosphere materials flows (see the figure‚ below)‚ which current chemistry education

C H A P T E R 5 Basic Concepts from Organic Chemistry 5.1 | INTRODUCTION The fundamental information that environmental engineers and scientists need concerning organic chemistry differs considerably from that which the organic chemist requires. This difference is due to the fact that chemists are concerned principally with the synthesis of compounds‚ whereas environmental engineers and scientists are concerned‚ in the main‚ with how the organic compounds in liquid‚ solid‚ and gaseous wastes
