An EDTA solution was prepared by dissolving approximately 4.0 g of disodium salt in approximately 1 L of water. An average 12.35 mL of this solution was required to titrate of a 25.00 mL aliquot of a standard that contained 0.8412 g of CaCO3 per liter. Titration of 30.00 mL mineral water sample required 11.54 mL of the EDTA solution using a calcium-specific indicator. Calculate the molarity of the EDTA solution and the concentration of CaCO3 in ppm.

A 1.000 mL aliquot of a solution containing Cu²+ and Ni²+ is treated with 25.00 mL of a 0.03703 M EDTA solution. The solution is then back titrated with 0.02138 M Zn²+ solution at a pH of 5. A volume of 22.13 mL of the Zn²+ solution was needed to reach the xylenol orange end point. A 2.000 mL aliquot of the Cu²+ and Ni²+ solution is fed through an ion-exchange column that retains Ni²+. The Cu²+ that passed through the column is treated with 25.00 mL of 0.03703 M EDTA. This solution required 18.53 mL of 0.02138 M Zn²+ for back titration.
