The dissociation degree is the fraction of original solute molecules that have dissociated. The degree of dissociation is the fraction of the original solute molecules that have dissociated. Zinc salts are usually fully dissociated in aqueous solution. An ionic equation is a chemical equation in which electrolytes are written as dissociated ions. A strong acid is one that is fully dissociated in aqueous solution. Hydrochloric acid is a strong acid, since it is completely dissociated in water. A strong base is one that is fully dissociated in aqueous solution. In the first step, water is dissociated into electrons, protons, and free oxygen. The complexes may be dissociated by thermal denaturation, also referred to as melting. Molecular gases may be dissociated by the plasma. Some salts are not fully dissociated in solution. At pH 13 or higher, the acid is completely dissociated as the phosphate ion, . Nitriding heats the steel part to in an atmosphere of ammonia gas and dissociated ammonia. Microtubules also destabilize when tau is dissociated. Laing, however, partially dissociated himself from his colleague Cooper's term "anti-psychiatry".
