Dissociation meaning chem
WebK D is the ratio of the antibody dissociation rate (k off), how quickly it dissociates from its antigen, ... [antigen]. The measurement of the reaction rate constants can be used to define an equilibrium or affinity constant (1/K D). In short, the smaller the K D value the greater the affinity of the antibody for its target. Web1 : the act or process of dissociating : the state of being dissociated: such as a : the …

Dissociation in chemistry is a general process in which molecules (or ionic compounds such as salts, or complexes) separate or split into other things such as atoms, ions, or radicals, usually in a reversible manner. For instance, when an acid dissolves in water, a covalent bond between an … See more For reversible dissociations in a chemical equilibrium the dissociation constant Kd is the ratio of dissociated to undissociated compound $${\displaystyle K_{d}=\mathrm {\frac {[A][B]}{[AB]}} }$$ See more The dissociation of salts by solvation in a solution, such as water, means the separation of the anions and cations. The salt can be recovered by evaporation of the solvent. An electrolyte refers to a substance that contains free ions … See more The reaction of an acid in water solvent is often described as a dissociation where HA is a proton acid such as acetic acid, CH3COOH.
