Solubility of Barium and Strontium Sulfates in Strong Electrolyte Solutions.

Environmental Sci and Technol 1971 Oct; 5(10):5 pages
Knowledge of the solubilities of baso4 and srso4 in solutions containing nacl, cacl2, mgcl2, and nahco3 is needed to solve geologic and petroleum production problems. Samples of the sulfates were tagged with sulfur-35 and prepared by precipitation. The solubility was measured in various concentrations of the major solutes by use of a liquid scintillation technique to detect the so4- -in solution. The observed solubilities plotted against strength of the solution are similar for strong electrolytes. They reach a maximum at concentration levels beginning at an ionic strength of near 1. The sulfate solubility in synthetic brines (principally nacl) confirms the ionic strength-sulfate solubility relationships.
