Chemical chameleon. The chemical chameleon is a redox reaction, well known from classroom demonstrations, that exploits the dramatic color changes associated with the various oxidation states of manganese. [1][2] Glauber reported the first description of the production of potassium permanganate when he noted that manganese dioxide (as the ...
A laboratory notebook (colloq. lab notebook or lab book) is a primary record of research. Researchers use a lab notebook to document their hypotheses, experiments and initial analysis or interpretation of these experiments. The notebook serves as an organizational tool, a memory aid, and can also have a role in protecting any intellectual ...
The iodine clock reaction is a classical chemical clock demonstration experiment to display chemical kinetics in action; it was discovered by Hans Heinrich Landolt in 1886. [1] The iodine clock reaction exists in several variations, which each involve iodine species ( iodide ion, free iodine, or iodate ion) and redox reagents in the presence of ...
The current ACELL project began as APCELL (Australian Physical Chemistry Enhanced Laboratory Learning) in the late 1990s. Initially funded by the Australian Government through its Committee for University Teaching and Staff Development (CUTSD) program, the aim of APCELL was to build a database of tested, educationally-sound undergraduate level ...
In chemistry, a template reaction is any of a class of ligand -based reactions that occur between two or more adjacent coordination sites on a metal center. In the absence of the metal ion, the same organic reactants produce different products. The term is mainly used in coordination chemistry. The template effects emphasizes the pre ...
Miller–Urey experiment. The Miller–Urey experiment was a synthesis of small organic molecules in a mixture of simple gases in a thermal gradient created by heating (right) and cooling (left) the mixture at the same time, with electrical discharges. The Miller–Urey experiment[ 1 ] (or Miller experiment[ 2 ]) was an experiment in chemical ...
Elephant's toothpaste. Elephant's toothpaste is a foamy substance caused by the rapid decomposition of hydrogen peroxide (H2O2) using potassium iodide (KI) or yeast and warm water as a catalyst. [1] How rapidly the reaction proceeds will depend on the concentration of hydrogen peroxide. [2][3][4]
NMR line broadening techniques. In chemistry, NMR line broadening techniques (or NMR line broadening experiments) can be used to determine the rate constant and the Gibbs free energy of exchange reactions of two different chemical compounds. If the two species are in equilibrium and exchange to each other, peaks of both species get broadened in ...
