Metal Complexes of Trifluoropentanedione. An Experiment for the General Chemistry Laboratory  Robert 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.

The Household Chemistry of Cleaning Pennies  Laurence D. Rosenhein
Although it is well known that solutions of vinegar and table salt are effective in removing tarnish from pennies, chemical explanations of this behavior are not included in sources of this "household chemistry" and erroneous explanations have crept into popular literature on this subject; this article provides some relevant empirical information on the system.
