Guys i am really confused - What is dissolution? please explain.

...Rates assured

Dissolution is the process by which a solid or liquid enters its aqueous phase solution. This can be explained simply as a breakdown of the crystal lattice into individual ions, atoms or molecules.

 Ionic Compounds

For ionic compounds, dissolution takes place when the component ions dissociate into its component parts. This normally occurs in polar solvents, such aswater or ammonia.

NaCl_(s) → Na⁺_(aq) + Cl^-_(aq)



In a colloidal dispersed system, ion dissolution arises, where the dispersed particles exist in equilibrium with their saturated counter part, i.e.



NaCl_(s) → Na⁺_(aq) + Cl^-_(aq)



The behavior of this system is characterised by the components activity coefficients and solubility product, i.e.







The ability of an ion to preferentially dissolve (as a result of unequal activities) is classified as the potential determining ion  This in turn results in the remaining particle possessing either a net positive/negative surface charge.

 Polar Compounds

Other compounds experience dissolution simply as a breakdown of their crystal lattice, and due to their polarity, or non-polarity, mix perfectly with the solvent.
