Question

(a) Barium ions are poisonous. Patients with digestive tract problems are sometimes given

Answer 1

The numerical value of the Ksp  of $BaSO_{4}$ is 1.69 * 10^-20.

What is the Ksp?

The Ksp is an equilibrium constant that shows the extent to which a substance is soluble in water. Now consider the fact that $BaSO_{4}$ is almost insoluble in water.

i) The Ksp of the $BaSO_{4}$ solution can be obtained from the relation;

Ksp = [$Ba^{2+}$] [$SO_{4}^{2-}$]

ii) The numerical value of the Ksp is obtained from; [1.30 × 10–10]^2 = 1.69 * 10^-20

iii) The reason for the toxicity of $BaCO_{3}$ even though it is not more soluble that barium sulfate is that $BaCO_{3}$ can dissolve in the gastrointestinal tract which is acidic leading to barium poisoning.
