Textbook Question

Chapter 17, Problem 100AE

Tooth enamel is composed of hydroxyapatite, whose simplest formula is Ca₅ (PO₄)₃OH, and whose corresponding K_a_p = 6.8 × 10-27. As discussed in the chemistry and Life box on page 746, fluoride in fluorinated water or in toothpaste reacts with hydroxyapatite to form fluoroapatite, Ca₅ (PO₄)₃F, whose K_a_p =1.0 × 10-60.

Write the expression for the solubility-constant for hydroxyapatite and for fluoroapatite.
Calculate the molar solubility of each of these compounds.
