Question
The following solubilities are reported in OpenStax Chemistry 2e, Exercise 15.10, in grams of compound per 100 mL of water. Using the exercise's assumption that dissolution does not change the volume, determine the solubility product of each salt.(a) BaSiF₆: 0.026 g per 100 mL; the anion is SiF₆²⁻.(b) Ce(IO₃)₄: 1.5 × 10⁻² g per 100 mL.(c) Gd₂(SO₄)₃: 3.98 g per 100 mL.(d) (NH₄)₂PtBr₆: 0.59 g per 100 mL; the anion is PtBr₆²⁻.

Evidence boundary
This is a representative solution to OpenStax Chemistry 2e Exercise 15.10 for the search topic “part ii equilibria involving sparingly soluble salts”; it is not an authenticated Part II laboratory handout or an experimental report. All four supplied solubilities are used unchanged. The calculations assume unchanged solution volume, the stated complex ions, and the textbook concentration-based dissolution model, with no additional equilibria or activity corrections. The source specifies no temperature, so none is assigned. No laboratory observations or independently measured Ksp values are invented.
