2. 25.00-mL aliquots of the solution in problem 1 are titrated with EDTA to the calmagite end point. A blank containing a small measured amount of Mg²+ requires 2.12 mL of the EDTA to reach the end point. An aliquot to which the same amount of Mg2+ is added requires 25.88 mL of the EDTA to reach the end point. How many mL of EDTA are needed to titrate the Ca2+ ion in the aliquot? а. mL b. How many moles of EDTA are there in the volume obtained in a.? - mol c. What is the molarity of the EDTA solution? - M
