A video of sodium chloride crystals dissolving and dissociating in water. 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.
Dissociation, in the wide sense of the word, is an act of disuniting or separating a complex object into parts.. Dissociation may also refer to: . Dissociation (chemistry), general process in which molecules or ionic compounds (complexes, or salts) split into smaller particles, usually in a reversible manner
Solubility equilibrium is a type of dynamic equilibrium that exists when a chemical compound in the solid state is in chemical equilibrium with a solution of that compound. The solid may dissolve unchanged, with dissociation, or with chemical reaction with another constituent of the solution, such as acid or alkali.
In practice, the mixture can be created by dissolving the acid in water, and adding the requisite amount of strong acid or base. When the p K a and analytical concentration of the acid are known, the extent of dissociation and pH of a solution of a monoprotic acid can be easily calculated using an ICE table .

A negative value for the enthalpy change of solution corresponds to an ion that is likely to dissolve, whereas a high positive value means that solvation will not occur. It is possible that an ion will dissolve even if it has a positive enthalpy value. The extra energy required comes from the increase in entropy that results when the ion ...
