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.

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 380 mL of a saturated barium sulfate solution, how much toxic Ba2+ ion has the patient consumed? The solubility product Ksp of BaSO4 is 1.10×10−10.

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 400 mL of a saturated barium sulfate solution, how much toxic Ba2+ ion has the patient consumed? The solubility product Ksp of BaSO4 is 1.1*10^-10 .

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?

Barium sulfate is so insoluble that it can be swallowed without significant danger, even though Ba2+ is toxic. At 25 °C, 1.00 L of water dissolves only 0.00245 g of BaSO4. Calculate the molar solubility and Ksp for BaSO4.

Barium Sulfate is used in medical imaging of the gastrointestinal tract. Its solubility product constant is...
Barium Sulfate is used in medical imaging of the gastrointestinal tract. Its solubility product constant is 1.08 x 10^(-8) at 25 degrees Celsius, so it's ideally suited for this purpose because of its low solubility when a "barium milkshake" is consumed by a patient. The pathways of sparingly soluble salts are easily monitored by X-rays. Will Barium Sulfate precipitate when 0.010 L of 0.0020 M Na2SO4 is added to 100.0 mL of BaCl2? You show all work and calculation to...

Part C: 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 380 mL of a...

Part A: How many grams of dry NH4Cl need to be added to 2.40 L of a 0.500 M solution of ammonia, NH3, to prepare a buffer solution that has a pH of 8.71? Kb for ammonia is 1.8×10^−5. Part B: A 75.0-mL volume of 0.200 M NH3 (Kb=1.8×10−5) is titrated with 0.500 M HNO3. Calculate the pH after the addition of 17.0 mL of HNO3.

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...
