Barium sulfate is swallowed to enhance the contrast of X-ray images of the gastrointestinal tract. 1) Calculate the solubility of Ba2+ in mol/L in pure water. Ksp of BaSO4 at 37 °C = 1.5 x 10-10. 2) In the stomach, the HCl concentration is 0.10 M. Calculate the solubility of Ba2+ in mol/L in this solution. Ka of HSO4- at 37 °C = 7.1 x 10-3.

A.) Barium sulfate, BaSO4, is used in medical imaging of the
gastrointestinal tract because it is opaque to X rays. A barium
sulfate solution, sometimes called a cocktail, is ingested by the
patient, whose stomach and intestines can then be visualized via
X-ray imaging. If a patient ingests 260 mL of a saturated barium
sulfate solution, how much toxic Ba2+ ion has the patient
consumed?
