We began the chapter with an informal discussion of how the mineral fluorite (as shown) is formed. Fluorite, CaF2, is a slightly soluble solid that dissolves according to the equation: CaF2(s) ⇌ Ca2+(aq) + 2F−(aq)The concentration of Ca2+ in a saturated solution of CaF2 is 2.15 × 10–4 M; therefore, that of F– is 4.30 × 10–4 M, that is, twice the concentration of Ca2+. What is the solubility product of fluorite?

As a chemist, you know that the formation of soluble silver-ammonium complex, in an AgCl solution, occurs in a 3-step process: If you want to find out the overall equilibrium constant, you multiply Kf and Ksp. If your Ksp is equal to 1.8 x 10-10 and your Kf is 1.80 x 107, what is your pKoa?
As part of the analysis of water samples, the hardness of water is commonly measured and calculated. It is commonly expressed in ppm by mass (parts per million) of CaCO3. Parts per million is also equivalent to milligrams of CACO3 per liter of water. In a sample taken by an environmentalist, he was able to observe a hardness count of 205 mg CacO3/L. Given this hardness count of the sample, what is the molar concentration of Ca2+ ions in the water sample?
