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 initial letters of a name, for example: cyanotrichite: Cya and mitscherlichite: Mits. A combination considered characteristic of the mineral name, for example: ewingite: Ewg and neighborite: Nbo. A selection of letters expressing components of the name, for example: adranosite = Arn and hellandite: Hld.
Dilute aqueous KSCN is occasionally used for moderately realistic blood effects in film and theatre. It can be painted onto a surface or kept as a colorless solution.
IUPAC states that, "As one of its major activities, IUPAC develops Recommendations to establish unambiguous, uniform, and consistent nomenclature and terminology for specific scientific fields, usually presented as: glossaries of terms for specific chemical disciplines; definitions of terms relating to a group of properties; nomenclature of chemical compounds and their classes; terminology ...
Creatine (/ ˈ k r iː ə t iː n / or / ˈ k r iː ə t ɪ n /) [1] is an organic compound with the nominal formula (H 2 N)(HN)CN(CH 3)CH 2 CO 2 H.It exists in various tautomers in solutions (among which are neutral form and various zwitterionic forms).

In chemistry, the term "turnover number" has two distinct meanings.. In enzymology, the turnover number (k cat) is defined as the limiting number of chemical conversions of substrate molecules per second that a single active site will execute for a given enzyme concentration [E T] for enzymes with two or more active sites. [1]
Chemical nomenclature however (with IUPAC nomenclature as the best example) is necessarily more restrictive: Its purpose is to standardize communication and practice so that, when a chemical term is used it has a fixed meaning relating to chemical structure, thereby giving insights into chemical properties and derived molecular functions. These ...
