![2+
Kidney stones can be indicated, in part, by elevated levels of calcium in urine. Ca is precipitated as
CaC204 H20, filtered, washed, and titrated with standardized KMnO4 according to the reaction:
2 MnO4 + 16 H+ + 5 C2042-→ 2 Mn2+ +8 H2O + 10 CO2.
A clinical technician obtained a 5.00-mL sample of urine from a patient. The calcium in urine was
precipitated out as calcium oxalate, CaC204, and then subsquently dissolved in acid. The resultant
mixture required 8.80 mL of 1.617 x 10 M KMnO4 to reach the colorless-to-pink end point.
In correct significant figures, the molar concentration of Ca2+ in the urine sample is 7.115 X 10E-3
