A 25.00 mL aliquot of the standard calcium solution described in Question 1 was titrated with a previously prepared EDTA solution. In the titration, 32.55 mL of the EDTA solution was required to reach the end point. What is the molarity of the EDTA? 2. 3. The concentration of Ca2+ in an unknown solution was determined by titration with the EDTA solution standardized in Question 2 above. In the determination, 25.00 mL of the unknown solution was diluted to 250.00 mL with deionized water. A 25.00 mL aliquot of the diluted solution was then titrated with the EDTA solution. The titration required 35.54 mL of the EDTA solution to reach the end point. What is the molarity of calcium in the original unknown solution? .olsul@U x , aso = .184(eX.353u4.04 e M
