Solubility of Barium and Strontium Sulfates in Strong Electrolyte Solutions.
ACS Preprints 1971 Mar; 11(1):115-124
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 s35 and prepared by precipitation. The solubility was measured in various concentrations of the major solutes by use of liquid scintillation technique to detect the so4 in solution. The observed solubilities plotted against ionic strength of the solution are similar for strong electrolytes. They reach a maximum at levels determined by ionic attraction and assciation, and presence of complex ions. The sulfate solubility in synthetic brines (principally nacl) confirms the ionic strength-sulfate solubility relationships.
