A solution of EDTA is prepared by dissolving 1.986 grams of solid in approximately 500 mL of water. A standard calcium ion solution is then prepared by dissolving 0.2191 grams of chelometric calcium carbonate in HCl until dissolved, evaporating off the solvent, then redissolving into a 250.0 mL volumetric flask. A 25.00 mL aliquot of this calcium solution required exactly 26.18 mL of the EDTA solution to reach an Eriochrome Balck T endpoint. What is the concentration of the EDTA solution
