The Acid Dissociation Constant is defined as a parameter that characterizes the electronic nature of molecules by quantifying the extent of dissociation of an acid into its conjugate base and proton. It is represented by the equation Ka = [A-][H+]/[HA] and is commonly expressed as pKa = ...

it is usually said that "an acid is ionized in water". In F.5/6 the term"dissociation constant" is more frequently used than the term"ionization constant" for the equilibrium constant ofdissociation/ionization of a weak acid/base in water. e.g. Na⁺Cl⁻(s) + ...
In this work, the pKa value of the dissolved humic acid fraction was determined on the basis of changes in the shape and intensity of their UV/VIS spectra measured in media with various values of pH. The shape of the spectra depends on the pH value, because acidic and alkaline media, ...
This method principle exemplifies a new approach for anti-isotype ADA assays, and could be an effective strategy for neutralizing antibody (NAb), pharmacokinetic (PK) and biomarker analysis in need of overcoming interference factors. 展开 关键词: Anti-drug antibody (ADA) Acid dissociation Electro...
The dissociation of weak electrolyte (a weak base or weak acid) is expressed in terms of Ostwald's dilution law. An acid is substance which furnishes a proton or accepts an electron pair, where a base is proton acceptor or electron pair donor. Stronger is acid, weaker is its conjugate bas...

The dissociation constant (pKa) helps to analyze the molecular structure and reaction mechanisms of amino acids and alkanolamines in an aqueous solution. The functional group of the amino acid is protonated if the pH of the system is below the corresponding pKa and deprotonated if the pH is abov...
