A BaSO4 slurry is ingested before the
gastrointestinal tract is x-rayed because it is opaque to x-rays
and defines the contours of the tract. Ba2+ ion is
toxic, but the compound is nearly insoluble. If ΔG° at
37°C (body temperature) is 75.0 kJ/mol for the process
what is [Ba2+] in the intestinal tract (multiply the
number you calculate by 106 and enter that number to 2
decimal places into the field)? (Assume that the only source of
SO42− is the...
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?
The solubility product Kspof BaSO4 is 1.10×10−10
