Shen, Jian; Deng, Shubo; Wu, Jing – Journal of Chemical Education, 2022
The undergraduates in the major of Environmental Science and Environmental Engineering frequently ignored the importance of identifying pollution sources for water environment monitoring and knew little about the techniques of identifying pollution sources. Thus, a laboratory experiment which focused on pollution sources identification in a water…

A class of 18 students attending the last year of an Italian high school was divided into groups and performed the extraction of pigments contained in hibiscus tea. Each group worked at a different temperature and carried out multiple extractions using distilled water as a solvent. By means of UV-vis spectroscopy it was possible to determine the…

Kirby, Matthew E.; Bullen, Jay C.; Hanif, M. D.; Heiba, Hany Fathy; Liu, Fengjie; Northover, George H. R.; Resongles, Eleonore; Weiss, Dominik J. – Journal of Chemical Education, 2020
Understanding the controls of the oxidation rate of iron (Fe) in oxygenated aquatic systems is fundamental for students of the Earth and Environmental Sciences as it defines the bioavailability of Fe, a trace metal essential for life. The laboratory experiment presented here was successfully developed and used during a third-year undergraduate lab…

This article highlights the multianalytical study of exuded liquid from an ancient Egyptian sealed alabaster vase by Master's students in an applied chemistry for cultural heritage course. Master students are introduced to the field of Archaeometry that see the collaboration of experts in different areas of research such as conservators, curators…

Chng, J. J. Kenneth; Patuwo, Michael Yudistira – Journal of Chemical Education, 2021
We described and ran a lesson plan for a build-your-own visible-range spectrophotometer undergraduate project as inspired by the research of Bougot-Robin, Imperial College London. Students were required to improve a basic Raspberry Pi spectrophotometer design and evaluate their improvements. Students learned firsthand how to manage instrumental…

A green chemistry experiment is presented for teaching an undergraduate quantitative analysis/analytical chemistry laboratory class through the use of black tea leaf extract for the determination of iron in supplement tablets. Dried tea leaf is a safe, low cost, and widely available source of natural extract that can be used in place of more toxic…

Kondratowicz, Izabela; Z?elechowska, Kamila – Journal of Chemical Education, 2017
The aim of this laboratory experiment is to utilize graphene oxide (GO) material to introduce undergraduate students to many well-known concepts of general chemistry. GO is a new nanomaterial that has generated worldwide interest and can be easily produced in every well-equipped undergraduate chemical laboratory. An in-depth examination of GO…

Sosabowski, Michael Hal; Olivier, George W. J.; Jawad, Hala; Maatta, Sieja – School Science Review, 2017
Natural products are ubiquitous in nature but do not form a large proportion of the A-level syllabuses in the UK. In this article we briefly discuss a small selection of natural products, focusing on alcohols, aldehydes and ketones, and alkaloids. We then outline two natural product experiments that are suitable for A-level chemistry clubs or…

Volmer, Dietrich A.; Curbani, Luana; Parker, Timothy A.; Garcia, Jennifer; Schultz, Linda D.; Borges, Endler Marcel – Journal of Chemical Education, 2017
This experiment describes a simple protocol for teaching acid-base titrations using potentiometry, conductivity, and/or photometry to determine end points without an added indicator. The chosen example examines the titratable acidity of a red wine with NaOH. Wines contain anthocyanins, the colors of which change with pH. Importantly, at the…

de Macedo, Adriana Nori; Mathiaparanam, Stellena; Ly, Ritchie; Britz-McKibbin, Philip – Journal of Chemical Education, 2018
New experiments for undergraduate students are needed to stimulate experiential learning in the laboratory while providing valuable training for future career development. Iodine deficiency remains a major public health concern that is monitored by measuring the median urinary iodide concentration of a population. In this context, we have…

Valente Nabais, J. M.; Costa, Sara D. – Journal of Chemical Education, 2017
This paper reports an experimental activity where students have to carefully analyze the evidence collected at the crime scene, namely fibers and lipstick traces. The fibers are analyzed by infrared spectroscopy, solubility tests, and optical microscopy, while in turn the lipstick traces are investigated by thin layer chromatography. Students also…

Diawati, Chansyanah; Liliasari; Setiabudi, Agus; Buchari – Journal of Chemical Education, 2018
Students learned the principles and practice of photometry through project-based learning. They addressed the challenge of measuring the unknown concentration of a colored substance using a photometer they were required to design, build, and test. Then, they used that instrument to carry out the experiment and fulfill the challenge. A photometer…
