Ferraro, Giovanni; Fratini, Emiliano – Journal of Chemical Education, 2019
A procedure for one-pot preparation and characterization of silver 1D nanostructures is described. The main advantages of this synthetic approach are the simplicity and reproducibility, where the size of the final product can be controlled just by changing the reaction time. This experiment is designed as a laboratory introduction to colloidal…

Warzecha, Evan; Berto, Timothy C.; Wilkinson, Chad C.; Berry, John F. – Journal of Chemical Education, 2019
A new undergraduate inorganic chemistry laboratory experiment is presented. An introduction of the spectrochemical series and ligand exchange is explored using the coordination complex dirhodium tetraacetate, Rh[subscript 2](OAc)[subscript 4]. Students have measured the absorption spectra of the Rh[subscript 2] complex in the presence of various…
