Dissociation (chemistry) - Wikipedia
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. The double arrow means that this is an equilibrium process, with dissociation and recombination occurring at the … See more • Bond-dissociation energy • Photodissociation, dissociation of molecules by photons (light, gamma rays, x-rays) See more The degree of dissociation in gases is denoted by the symbol $${\displaystyle \alpha }$$, where $${\displaystyle \alpha }$$ refers to the percentage of gas molecules which dissociate. Various relationships between $${\displaystyle K_{p}}$$ See more Fragmentation of a molecule can take place by a process of heterolysis or homolysis. See more Receptors are proteins that bind small ligands. The dissociation constant Kd is used as indicator of the affinity of the ligand to the receptor. The … See more WebAs shown in the equation, dissociation makes equal numbers of hydrogen (H + ^+ + start superscript, plus, end superscript) ions and hydroxide (OH − ^-− start superscript, minus, end superscript) ions.While the hydroxide … jimmy hartwig twitter
