Textbook Question
Chapter 16, Problem 83AE
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?
