Before performing an analysis of calcium in a powdered cement sample with an EDTA titration, the EDTA must be standardized. A 50.0 mL known solution of 5.67 x 10-3 M Ca2+(aq) required 38.10 mL of an unknown EDTA solution to reach its end point. Based on the above data, what would be the correct molarity (MEDTA) of the solution?

  • 0.00289 M
  • 0.00357 M
  • 0.00524 M
  • 0.00744 M
  • 0.00849 M
