Dissociation example sentences

In accordance with the Le Chatelier's principle, the concentration stress of removed Fe3+ is relieved by dissociation of [Fe(SCN)]2+ to replenish the Fe3+ ions.Dissociation involves feelings of unreality, estrangement, depersonalisation, and sometimes a loss or shift of identity.Consider the two acids HA and H3O+ present in the above mentioned acid-dissociation equilibrium.Dissociation refers to the process of separation of ions in water already existing as such in the solid state of the solute, as in sodium chloride.Let us take thermal dissociation of calcium carbonate which is an interesting and important example of heterogeneous chemical equilibrium.For most of the ionic compounds, ?sol H0 is positive and the dissociation process is endothermic.The bond dissociation enthalpy is the change in enthalpy when one mole of covalent bonds of a gaseous covalent compound is broken to form products in the gas phase.He received Nobel Prize in Chemistry in 1903 for his theory of electrolytic dissociation and its use in the development of chemistry.It can be defined as a shift in equilibrium on adding a substance that provides more of an ionic species already present in the dissociation equilibrium.H2A being a strong acid, the primary reaction involves the dissociation of H2 A, and H3O+ in the solution comes mainly from the first dissociation step.In a weak base there is partial ionization of MOH into M+ and OH–, the case is similar to that of acid-dissociation equilibrium.But, broadly speaking we can say that the extent of dissociation of an acid depends on the strength and polarity of the H-A bond.The terms dissociation and ionization have earlier been used with different meaning.As the concentration of water remains constant it has been omitted from the denominator and incorporated within the dissociation constant.Thus if we take a saturated solution of sodium chloride and pass HCl gas through it, then sodium chloride is precipitated due to increased concentration (activity) of chloride ion available from the dissociation of HCl.
