ABSTRACT

Assuming that the activity of the solution is proportional to the molar concentration, Equation 13.1 can be rewritten as

log .

(13.2)

The size and shape of fine particles (diameter, @μm) affect the solubility, which increases with decreasing particle size as predicted by Equation 13.2.
