Tooth Enamel Is Composed of the Mineral Hydroxyapatite

question 38

Multiple Choice

Tooth enamel is composed of the mineral hydroxyapatite. It is essentially insoluble in water with K_sp  2.3  10^59, but it reacts with weak acids in the mouth as described by one of the reaction equations below. You can determine the equilibrium constant, K, for this reaction from K_sp and K_w (the equilibrium constant for water autoionization, K_w  1.0  10^14) . What is the value of K?
