  2. Anticline - Wikipedia

    en.wikipedia.org/wiki/Anticline

    An anticlinorium is a large anticline in which a series of minor anticlinal folds are superimposed. Examples include the Late Jurassic to Early Cretaceous Purcell Anticlinorium in British Columbia [1] and the Blue Ridge anticlinorium of northern Virginia and Maryland in the Appalachians, [6] or the Nittany Valley in central Pennsylvania.

  3. List of purification methods in chemistry - Wikipedia

    en.wikipedia.org/wiki/List_of_purification...

    Recrystallization: In analytical and synthetic chemistry work, purchased reagents of doubtful purity may be recrystallised, e.g. dissolved in a very pure solvent, and then crystallized, and the crystals recovered, in order to improve and/or verify their purity.

  4. The Chemical History of a Candle - Wikipedia

    en.wikipedia.org/wiki/The_Chemical_History_of_a...

    Title page to the first edition. Intended for young beginners, for whom it is well adapted, as an introduction to the study of chemistry. [3]According to Frank Wilczek: . It is a wonderful laying-bare of surprising facts and intricate structure in a (superficially) familiar process — the burning of a candle.

  5. Iodine clock reaction - Wikipedia

    en.wikipedia.org/wiki/Iodine_clock_reaction

    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 ...

  6. Design of experiments - Wikipedia

    en.wikipedia.org/wiki/Design_of_experiments

    This example of design experiments is attributed to Harold Hotelling, building on examples from Frank Yates. [21] [22] [14] The experiments designed in this example involve combinatorial designs. [23] Weights of eight objects are measured using a pan balance and set of standard weights. Each weighing measures the weight difference between ...

  7. 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 ...

  8. Glossary of chemistry terms - Wikipedia

    en.wikipedia.org/wiki/Glossary_of_chemistry_terms

    Also acid ionization constant or acidity constant. A quantitative measure of the strength of an acid in solution expressed as an equilibrium constant for a chemical dissociation reaction in the context of acid-base reactions. It is often given as its base-10 cologarithm, p K a. acid–base extraction A chemical reaction in which chemical species are separated from other acids and bases. acid ...

  9. Markovnikov's rule - Wikipedia

    en.wikipedia.org/wiki/Markovnikov's_rule

    The rule states that with the addition of a protic acid HX or other polar reagent to an asymmetric alkene, the acid hydrogen (H) or electropositive part gets attached to the carbon with more hydrogen substituents, and the halide (X) group or electronegative part gets attached to the carbon with more alkyl substituents.
