The solubility product for BaSO4, at 18-25°C is:
Correct answer: A. 1.0 x 10^-10 mol2dm-6
- A. 1.0 x 10^-10 mol2dm-6
- B. 8.7 x 10^-36 mol2dm-6
- C. 1.8 x 10^-21 mol2dm-6
- D. 8.4 x 10^-28 mol2dm-6
- E. 3.5 x 10^-52 mol2dm-6
Explanation
The solubility product for BaSO4 represents the equilibrium constant for its dissolution reaction. At 18-25°C, BaSO4 has a very low solubility, resulting in a small concentration of Ba²+ and SO4²- ions in solution, which yields a solubility product of 1×10¹⁰mol²dm-6.

About Solutions and Colloids
Solutions are described using molarity, molality, normality, mole fraction, percentage concentration and parts per million. Coverage also includes vapour-pressure lowering, boiling-point elevation, freezing-point depression and osmotic pressure, then distinguishes true solutions, colloids and suspensions by particle size, stability, light scattering and settling.
