Teaching Lab Report Writing through Inquiry: A Green Chemistry Stoichiometry Experiment for General Chemistry. Halász N, Párducz A, Karnushina I, Tóth I, Joó F. The fine structural characteristics of ZIO reaction was studied in the cerebral and cerebellar cortex and olfactory bulb of the rat and in synaptosomes prepared from rat cerebellar cortex. Citations are the number of other articles citing this article, calculated by Crossref and updated daily. Find more information about Crossref citation counts. Get article recommendations from ACS based on references in your Mendeley library. In the first experiment, students draw upon their understanding of solubility and molarity to propose a synthesis of zinc iodide from a double replacement reaction involving zinc sulfate and barium iodide. Explain why some zinc was left over at the end of the reaction and why you think the amounts were selected to have zinc left over. By referring to the literature and conducting qualitative tests, students determine that the white product is zinc hydroxide, a base produced from the hydrolysis of zinc ion. Controlling Solid–Liquid Conversion Reactions for a Highly Reversible Aqueous Zinc–Iodine Battery. 6...10 times more synaptic vesicles were stained by ZIO in the inhibitory terminals than in the excitatory ones. from the ACS website, either in whole or in part, in either machine-readable form or any other form Please reconnect. the Altmetric Attention Score and how the score is calculated. Get article recommendations from ACS based on references in your Mendeley library. Experientia. It needs almost 4 times the grams of iodine as it needs zinc. (optional) Were your observations on the electrolysis consistent with your expectations? not otherwise permitted to reproduce, republish, redistribute, or sell any Supporting Information Students compare the double replacement reaction with the elemental synthesis in terms of percentage yield, efficiency, safety, and cost. 3.

Significance of the maillet method (ZIO) for cytochemical studies of subcellular structures. Subsequent reaction with an excess of Grignard reagent from bromobenzene afforded the (3R) ... Chlor-zinc iodide histochemistry, while an unreliable indicator for cellulose, remains the only way to indicate the wall chemistry of endobiotic parasites. This procedure involves the in situ formation of arylzinc reagents.

Department of Curriculum and Instruction, Department of Chemistry, Hunter College of the City University of New York, New York, NY 10021. These two experiments could be of interest to introductory chemistry instructors at the college or high school level who teach their students about limiting and excess stoichiometry as well as acid–base chemistry. Teaching Lab Report Writing through Inquiry: A Green Chemistry Stoichiometry Experiment for General Chemistry. In the second experiment, students are asked to identify a white precipitate that forms during a synthesis of zinc iodide from its elements when a specific reagent, acetic acid, is not used. You’ve supercharged your research process with ACS and Mendeley! The inquiry-based experiments center on alternate reaction pathways involving a second synthesis of zinc iodide and a side reaction that produces zinc hydroxide.

E. Le Gall, A. Decompte, T. Martens, M. Troupel, Synthesis, 2010, 249-254. Organelles of different nerve cell types exhibit different ZIO reactions provided that the impregnation was carried out under standardized conditions. Iodine, however, could not always be found. 1977 Jan 15;33(1):1-10. doi: 10.1007/BF01936720. Find more information on the Altmetric Attention Score and how the score is calculated. Kristen L.
