Metal Complexes of Trifluoropentanedione. An Experiment for the General Chemistry LaboratoryRobert C. Sadoski, David Shipp, and Bill Durham Investigation of the transition-metal complexes produced by the reactions of Cr(III), Mn(II), Fe(III), Co(II), Ni(II), and Cu(II) with 1,1,1-trifluoro-2,4-pentanedione; mass spectroscopy is used to determine the stoichiometry of the reaction products. Sadoski, Robert C.; Shipp, David; Durham, Bill. J. Chem. Educ.2001, 78, 665.

Chromium Pollution: An Experiment Adapted for Freshman Engineering StudentsPenny Seymour Students analyze water samples contaminated with Cr(VI) to determine which of several industries appears to be the source of the contamination. The adaptation involves requiring the students to develop the analytic procedure themselves, rather than working from a prepared set of instructions, and then to report the results as a letter plus appendices, including general recommendations for remedial action, directed to the client who contracted the investigation. Seymour, Penny. J. Chem. Educ.1999, 76, 927.
