3. Calcium phosphate is one of the two main compounds that can precipitate out of urine to form kidney stones. The Ksp of calcium phosphate is 2.07 x 10 33 a) What is the molar solubility of calcium phosphate? b) If the Ca2 concentration in a person's urine is 150 mg/L, what concentration of phosphate in the urine (in mg/L) would be necessary for calcium phosphate to precipitate? c) The Ksp value given above is for room temperature (25 C). Would you expect your answer to part b) to be larger or smaller for the precipitation reaction taking place at body temperature (37 C)? Explain your answer in 1-2 sentences.
