The effect of ionic strength on the
solubility s of BaSO 4.In other cases where solute ions react with OH– or H 3 O+, a more complex pattern can arise, as in the
example of calcium oxalate in which the solubility increases as the pH is lowered.
Rates of Precipitate Formation and Particle Growth
The rate at which a precipitate can be produced in a filterable form varies widely and depends upon the
solution environment. In the case of the
