A constant-composition techinque has been used to study the kinetic ofdissolution of barium fluoride in which the activities of the lattice ions weremaintained constant during the experiments.The method enables kinetic datato be obtained at very low undersaturation.A striking change in the mecha-nism of dissolution is observed as the driving force is changed.At higher
