Our Everyday Cup of Coffee: The Chemistry behind Its Magic Marino Petracco Coffee beverages are so popular all over the world that there is hardly any need to describe them. But underlying this seemingly commonplace beverage there is a whole realm worth serious scientific study. The complexity of the raw seed matrix, made even more intricate when roasted, requires a deep understanding of its chemical nature. While coffee is not consumed for nutritional purposes, it is appreciated for its taste appeal along with its stimulating effects on mental and physical activity. The attention to quality is of paramount importance to both of these aspects to supply the customers with a pleasant and wholesome product. Petracco, Marino. J. Chem. Educ. 2005, 82, 1161.

Measuring Soil Phosphates Using Ion-Exchange Resins: A Final Project for Freshman Chemistry Donald A. Storer and A. M. Sarquis A model final project for freshman chemistry that uses a discovery-based scenario is described. The effect of solubility of compounds in a practical application is illustrated by allowing the student to discover that limestone (calcium carbonate) will react with phosphates in soils to produce insoluble compounds. The phosphate in the soil is isolated by a mixed-bed, anion-cation exchange resin capsule and analyzed spectrophotometrically. Storer, Donald A.; Sarquis, Arlyne M. J. Chem. Educ. 2000, 77, 748.

Fluorimetric analysis of nitrate in real samples Miguel, Antonio H.; Braun, Robert D. The fluorimetric analysis of "real" samples is often undesirable as a student experiment, since prior separations of elaborate sample preparations are required. It is the purpose of this paper to report a fluorimetric, student experiment for the determination of trace nitrate in river water and soil. Miguel, Antonio H.; Braun, Robert D. J. Chem.
