A 1.000 mL. aliquot of a solution containing Cu" and Ni²* is treated with 25.00 ml. of a 0.03468 M EDTA solution. The solution is then back titrated with 0.02308 M Zn* solution at a pH of 5. A volume of 20.28 ml. of the Zn²* solution was needed to reach the xylenol orange end point. A 2.000 mL aliquot of the Cu³* and Ni²* solution is fed through an ion- exchange column that retains Ni*. The Cut that passed through the column is treated with 25.00 ml. of 0.03468 M EDTA. This solution required 23.18 mL of 0.02308 M Zn* for back titration. The Ni* extracted from the column was treated witn 25.00 mL of 0.03468 M EDTA. How many milliliters of 0.02308 M Zn²* is required for the back titration of the Ni" solution? volume: ml.
