Chapter 18, Problem 18.74(choose chapter or problem)
Calcium oxalate (CaC2O4) is insoluble in water. This property has been used to determine the amount of Ca21 ions in blood. The calcium oxalate isolated from blood is dissolved in acid and titrated against a standardized KMnO4 solution as described in 18.72. In one test, it is found that the calcium oxalate isolated from a 10.0-mL sample of blood requires 24.2 mL of 9.56 3 1024 M KMnO4 for titration. Calculate the number of milligrams of calcium per milliliter of blood.
