  2. Crossover experiment (chemistry) - Wikipedia

    en.wikipedia.org/wiki/Crossover_experiment...

    Crossover experiments allow for experimental study of a reaction mechanism. Mechanistic studies are of interest to theoretical and experimental chemists for a variety of reasons including prediction of stereochemical outcomes, optimization of reaction conditions for rate and selectivity, and design of improved catalysts for better turnover number, robustness, etc. [6] [7] Since a mechanism ...

  3. Glycerol and potassium permanganate - Wikipedia

    en.wikipedia.org/wiki/Glycerol_and_potassium...

    The exothermic (heat producing) reaction between potassium permanganate (KMnO 4), a strong oxidizing agent, and glycerol (C 3 H 5 (OH) 3), a readily oxidised organic substance, is an example of an experiment sometimes referred to as a "chemical volcano". [7] [8]

  4. Blue bottle experiment - Wikipedia

    en.wikipedia.org/wiki/Blue_bottle_experiment

    The chemical reactions and mechanism in the blue bottle experiment rely on the oxidation of a sugar with the aid of air and a redox dye in a basic solution. Other variations of this reaction have been reported that use four families of redox dyes: thiazines , oxazines , azines , and indigo carmine have all been reported to work with glucose and ...

  6. Screaming jelly babies - Wikipedia

    en.wikipedia.org/wiki/Screaming_jelly_babies

    The experiment is practiced in schools around the world and is often used at open evenings to show the more engaging and entertaining aspects of science in secondary education settings. [2] [3] The experiment shows the amount of energy there is in a piece of candy. Jelly babies [4] or gummy bears [5] are often used for theatrics.

  7. Briggs–Rauscher reaction - Wikipedia

    en.wikipedia.org/wiki/Briggs–Rauscher_reaction

    Oscillogram made in July 1972 by Briggs and Rauscher. The Briggs–Rauscher oscillating reaction is one of a small number of known oscillating chemical reactions.It is especially well suited for demonstration purposes because of its visually striking colour changes: the freshly prepared colourless solution slowly turns an amber colour, then suddenly changes to a very dark blue.

  8. Chemical chameleon - Wikipedia

    en.wikipedia.org/wiki/Chemical_chameleon

    The chemical chameleon reaction shows the process in reverse, by reducing violet potassium permanganate first to green potassium manganate and eventually to brown manganese dioxide: [1] [2] [5] KMnO 4 (violet) → K 2 MnO 4 (green) → MnO 2 (brown/yellow suspension) Blue potassium hypomanganate may also form as an intermediate. [6]

  9. Chemical garden - Wikipedia

    en.wikipedia.org/wiki/Chemical_garden

    A chemical garden is a set of complex biological-looking structures created by mixing inorganic chemicals. This experiment in chemistry is usually performed by adding metal salts, such as copper sulfate or cobalt(II) chloride , to an aqueous solution of sodium silicate (otherwise known as waterglass).
