  2. Dissociation (chemistry) - Wikipedia

    en.wikipedia.org/wiki/Dissociation_(chemistry)

    The degree of dissociation in gases is denoted by the symbol α, where α refers to the percentage of gas molecules which dissociate. Various relationships between K p and α exist depending on the stoichiometry of the equation. The example of dinitrogen tetroxide (N 2 O 4) dissociating to nitrogen dioxide (NO 2) will be taken.

  3. Dissociation rate - Wikipedia

    en.wikipedia.org/wiki/Dissociation_rate

    Substrate dissociation rate contributes to how large or small the enzyme velocity will be. [2] In the Michaelis-Menten model, the enzyme binds to the substrate yielding an enzyme substrate complex, which can either go backwards by dissociating or go forward by forming a product. [2] The dissociation rate constant is defined using K off. [2]

  4. Dissociation constant - Wikipedia

    en.wikipedia.org/wiki/Dissociation_constant

    In chemistry, biochemistry, and pharmacology, a dissociation constant (K D) is a specific type of equilibrium constant that measures the propensity of a larger object to separate (dissociate) reversibly into smaller components, as when a complex falls apart into its component molecules, or when a salt splits up into its component ions.

  5. Lab notebook - Wikipedia

    en.wikipedia.org/wiki/Lab_notebook

    Lab notebook with the complete record of the experiments underlying a published paper. [1] Chemistry stencils that used to be used for drawing equipment in lab notebooks. A laboratory notebook (colloq. lab notebook or lab book) is a primary record of research.

    If nothing is specified, the equation is rendered in the same display style as "block", but without using a new paragraph. If the equation does appear on a line by itself, it is not automatically indented. The sum = converges to 2. The next line-width is disturbed by large operators. Or: The sum

  7. Acid dissociation constant - Wikipedia

    en.wikipedia.org/wiki/Acid_dissociation_constant

    Stepwise dissociation constants are each defined for the loss of a single proton. The constant for dissociation of the first proton may be denoted as K a1 and the constants for dissociation of successive protons as K a2, etc. Phosphoric acid, H 3 PO 4, is an example of a polyprotic acid as it can lose three protons.

  8. Solvation - Wikipedia

    en.wikipedia.org/wiki/Solvation

    The equilibrium constant for this dissociation can be predicted by the change in Gibbs energy of this reaction. The Born equation is used to estimate Gibbs free energy of solvation of a gaseous ion. Recent simulation studies have shown that the variation in solvation energy between the ions and the surrounding water molecules underlies the ...

  9. Acid–base titration - Wikipedia

    en.wikipedia.org/wiki/Acid–base_titration

    = = Where K b is the base dissociation constant, K w is the water dissociation constant. 4. The pH after the equivalence point depends on the concentration of the conjugate base of the weak acid and the strong base of the titrant. However, the base of the titrant is stronger than the conjugate base of the acid.
