The thermodynamic solubility products of strontium sulfate and strontium ca
rbonate in aqueous solution were determined experimentally. At 25 degreesC,
they are equal to 3.54 x 10(-10) and 2.15 x 10(-7), respectively. The ther
modynamic stability constants for SrCO30 and SrSO40 complexes were calculat
ed; at 25 degreesC, they are 1.86 x 10(4) and 111, respectively.
