Tooth enamel is composed of the mineral hydroxyapatite. The Ksp of hydroxyapatite, Ca5(PO4)3OH, is 6.8 × 10−37. Calculate the solubility of hydroxyapatite in pure water in moles per liter. How is the solubility of hydroxyapatite affected by adding acid? When hydroxyapatite is treated with fluoride, the mineral fluorapatite, Ca5(PO4)3F, forms. The Ksp of this substance is 1 × 10−60. Calculate the solubility of fluorapatite in water. How do these calculations provide a rationale for the fluoridation of drinking water?

- Many natural processes can be studied in the laboratory but only in an environment of controlled pH. Which of these combinations is the best to buffer the pH at approximately 7? Explain your choice. H3PO4/NaH2PO4 NaH2PO4/Na2HPO4 Na2HPO4/Na3PO4arrow_forwardMixtures of metal ions in aqueous solution can sometimes be separated by selective precipitation. What is selective precipitation? If a solution contained 0.10 M Mg2+, 0.10 M Ca2+, and 0. 10 M Ba2+, how could addition of NaF be used to separate the cations out of solutionthat is, what would precipitate first, then second, then third? How could addition of K3PO4 be used to separate out the cations in a solution that is 1.0 M Ag+, 1.0 M Pb2+, and 1.0 M Sr2+?arrow_forwardSilver chromate, Ag2CrO4, is an "insoluble" substance with a Ksp value of 1.2 x 10^-12.

Derive an equation for the concentration of Al3+ in water as a function of pH if the water is saturated with Al(OH)3. If the concentration of Al3+ in water cannot exceed 10 micromolar (because all the aluminum has dissolved), at what pH would you expect the product of the Al3+ concentration and the PO43− concentration to be a maximum? Explain your reasoning.arrow_forward
