Calcium phosphate (Ca3(PO4)2; MM = 310.18 g/mol), a large component of human bones and teeth, has a Ksp of 2.07 × 10-³3 at 25 °C. A. Write the reaction equation for the dissolution of Ca3(PO4)2 solid (in your solution sheet). B. Calculate the solubility in mg/L at 25 °C in pure water. Neglect other competing equilibria. C. Calculate the solubility in mg/L at 25 °C in the presence of 0.010 M CaCl₂. Neglect other competing equilibria. Assume that 35 << 0.010 M. D. Is the assumption that s << 0.010 M valid? (Yes or No)
