This set of experiments provides an introduction to simple inorganic synthesis and qualitative analysis of inorganic pigments. I have taught this series of experiments in my first semester junior level inorganic class for the past 5 years. In part 1, students synthesize five inorganic pigments. Part 2 involves identifying an unknown inorganic white pigment by chemical and physical tests. These
This is a lab experiment designed to cover an array of techniques, including metal complex synthesis, spectroscopy and electrochemistry. Overall, the goal is to synthesize the metal complex Ru(bpy)32+, exchange the counter ion to demonstrate changes in solubility, absorbance and emission properties (including excited state quenching through energy and electron transfer, and ground state oxidation), as well as cyclic voltammetry of the complex.
I am sure most people already use this but I always refer to students to the Organometallic hypertext book. It has excellent explanations of topics such as back-donation in organometallic complexes.
Early in 2009, Christopher Cummins’ group at MIT reported (in Science) the synthesis of AsP3, a compound that had never been isolated at room temperature. Later that year, a full article was published in JACS comparing the properties and reactivity of AsP3 to those of its molecular cousins, P4 and As4. The longer article is full of possibilities for discussion in inorganic chemistry courses, with topics including periodic trends, NMR, vibrational spectroscopy, electrochemistry, molecular orbital theory, and coordination chemistry.

This activity leads students through the synthesis of compound nanoparticles and examines how key physical properties such as band gap vary with particle size. Prior to doing this, students should have some exposure to the structure of solids, band theory, and band gap as a periodic property (see, for example, Lisensky, et al. J Chem.
