Abstract
Barium sulfate solubility in diluted Na2SO4–NaNO3 solutions and seawater of 35‰ salinity at 22°C was studied in experiments. The value obtained for the thermodynamic solubility product of barium sulfate was $$L_{{{\text{BaSO}}_{4}^{0}}}^{0}$$ = (7.57 ± 0.87) × 10–11. It was shown that equilibrium concentration of dissolved barium in seawater was 30.7 μg/L and the water mass of the World Ocean was slightly undersaturated in BaSO4. The experimental data were used to determine the values of the mean ionic activity coefficient of BaSO4, total activity coefficient, and fractions of free Ва2+ ions in seawater: 0.108, 0.131, and 0.59, respectively.
