  2. Equilibrium constant - Wikipedia

    en.wikipedia.org/wiki/Equilibrium_constant

    The equilibrium constant of a chemical reaction is the value of its reaction quotient at chemical equilibrium, a state approached by a dynamic chemical system after sufficient time has elapsed at which its composition has no measurable tendency towards further change.

  3. Determination of equilibrium constants - Wikipedia

    en.wikipedia.org/wiki/Determination_of...

    When this definition is used, it is implied that the quotient of activity coefficients has a numerical value of one. It then appears that the equilibrium constant, K A {\displaystyle K_{A}} has the dimension 1/concentration, but that cannot be true since the standard Gibbs free energy change, Δ G ⊖ {\displaystyle \Delta G^{\ominus }} is ...

    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 ...

  5. Chemical equilibrium - Wikipedia

    en.wikipedia.org/wiki/Chemical_equilibrium

    In a chemical reaction, chemical equilibrium is the state in which both the reactants and products are present in concentrations which have no further tendency to change with time, so that there is no observable change in the properties of the system. [1]

  6. Acid dissociation constant - Wikipedia

    en.wikipedia.org/wiki/Acid_dissociation_constant

    In chemistry, an acid dissociation constant (also known as acidity constant, or acid-ionization constant; denoted ⁠ ⁠) is a quantitative measure of the strength of an acid in solution. It is the equilibrium constant for a chemical reaction

  7. Potassium chloride - Wikipedia

    en.wikipedia.org/wiki/Potassium_chloride

    Potassium chloride (KCl, or potassium salt) is a metal halide salt composed of potassium and chlorine.It is odorless and has a white or colorless vitreous crystal appearance. The solid dissolves readily in water, and its solutions have a salt-like taste.

    “Old vine” is a commonly used term in the world of high-end wine. It seems to imply something regal about a wine, a greater sense of depth, concentration or profundity of character.

  9. Extent of reaction - Wikipedia

    en.wikipedia.org/wiki/Extent_of_reaction

    In physical chemistry and chemical engineering, extent of reaction is a quantity that measures the extent to which the reaction has proceeded. Often, it refers specifically to the value of the extent of reaction when equilibrium has been reached.
