Designing a Self-Contained Qualitative Analysis Test for Transition Metal Ions  Y. S. Serena Tan, B. H. Iain Tan, Hian Kee Lee, Yaw Kai Yan, and T. S. Andy Hor
A challenging self-contained qualitative analysis test for transition metal compounds comprising nine unknowns whereby the unknown solutions can be systematically identified, without relying on external reagents, by inter-mixing the unknown samples. The names of the samples are made known, but their correspondence with the samples is concealed. A representative range of transition metal compounds was selected, together with two complementary main-group compounds. This "9-bottle" test encourages logical deduction and analytical thinking.

Complexometric Titrations: Competition of Complexing Agents in the Determination of Water Hardness with EDTA  M. Cecilia Yappert and Donald B. DuPre
The competition of complexing agents for the same metal ion and the formation of colored metal-ion complexes is demonstrated with the use of an overhead projector. This demonstration can be used to emphasize both the relevance of the relative values of formation constants in the complexation of metal cations and the applicability of complexometric titrations in quantitative chemical analysis.
