Problem: Barium sulfate is a contrast agent for X-ray scans that are most often associated with the gastrointestinal tract. Calculate the mass of BaSO4 that can dissolve in 100.0 mL of solution. The Ksp value for BaSO4 is 1.5 X 10-9.

FREE Expert Solution

The dissociation of BaSO4 in water is as follows:


The sulfate ion, SO42, has a charge of –2. Barium then has a charge of +2:

BaSO4(s)  Ba2+(aq) + SO42(aq)



We can construct an ICE table for the dissociation of BaSO4
