1. What is the balanced net ionic equation for the equilibrium involving the solutbility of Mg (OH)2? 2. When heating the mixture it had no color and the reaction was declared endothermic. Is the forward reaction endothermic or exothermic and why? What is the balanced net ionic equation when heat is included? 3. Most solids are more soluable in warm water than cold water. Does the soluability of Mg (OH)2 fit this pattern? Why?

Tooth enamel consists of hydroxyapatite, Ca5(PO4)3OH (Ksp = 8 × 10−37). Fluoride ion added to toothpaste and also drinking water reacts with Ca5(PO4)3OH to form the more tooth decay–resistant fluorapatite, Ca5(PO4)3F (Ksp = 1.0 × 10−60). Fluoridated water has dramatically decreased cavities among children. Calculate the solubility of Ca5(PO4)3OH and of Ca 5(PO4)3F in water.
