Question

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.

Answer 1

Answer: To Determine the amount of barium which was consumed by the patient let us Consider the reaction is given as followes: BaSO4(s) = Baltlaq) + Sony Vaq) → Ksp = [Ba2+] (son) kesp = (2) lx) kesp = x² lesp = 111 x 10 10 given x² = 1.1810-10 x=51x1010 x = 1:05 8105 molle Solution : 380ml -0.380L No ot moles of Ba2+ = 1005x105 401380 = 3.99 x10 6 mol

Now, Mass of Bart consumed = 13.99 x10 mai) (137.33 g/mol) = 5.479 10 g - 0.5479 ng Therefore, The amount of barium consumed by patient is / 0.5479 mg
