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?

2) Rank the salts in order of increasing Ksp
(remember 10–10 < 10–5)
3) If these rankings are not in the same order, why might
Ksp not always scale directly with molar solubility?
