Abstract
In their paper, Wu and Nancollas (WN) (Wu W., Nancollas H. 1998. A New Understanding of the Relationship between Solubility and Particle Size. J. Sol. Chem. 27:521-531) discussed the validity of the Ostwald-Freundlich equation when used for description of the relationship between the size of a particle and its solubility. We show that the reasoning and the main conclusions in the paper by WN are incorrect-regardless of the actual shape of the particle. We present derivations for the case where the particle is spherical as well as for the case of a general polyhedral shape. We show that in either case the Ostwald-Freundlich equation is valid, without any restrictions, for all cases discussed by WN.
