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 ...
The chemical reaction called Sharpless asymmetric dihydroxylation can be used to produce chiral diols from alkenes using an osmate reagent and a chiral catalyst. Another method is the Woodward cis-hydroxylation (cis diol) and the related Prévost reaction (anti diol), which both use iodine and the silver salt of a carboxylic acid.
Chemical reactions are usually characterized by a chemical change, and they yield one or more products, which usually have properties different from the reactants. Reactions often consist of a sequence of individual sub-steps, the so-called elementary reactions, and the information on the precise course of action is part of the reaction mechanism.
A domino effect is the cumulative effect produced when one event sets off a series of similar [1] or related events, a form of chain reaction. The term is an analogy to a falling row of dominoes . It typically refers to a linked sequence of events where the time between successive events is relatively short.
The French Revolution gave the English language three politically descriptive words denoting anti-progressive politics: (i) "reactionary", (ii) "conservative", and (iii) "right". "Reactionary" derives from the French word réactionnaire (a late 18th-century coinage based on the word réaction , "reaction") and " conservative " from conservateur ...

This requires mixing the compounds in a reaction vessel, such as a chemical reactor or a simple round-bottom flask. Many reactions require some form of processing ("work-up") or purification procedure to isolate the final product. [1] The amount produced by chemical synthesis is known as the reaction yield.
