Chemistry

A 1.000-mL aliquot of a solution containing Cu2 and Ni2 istreated with 25.00 mL of a 0.04503 M EDTA solution. The solution isthen back titrated with 0.02327 M Zn2 solution at a pH of 5. Avolume of 22.80 mL of the Zn2 solution was needed to reach thexylenol orange end point. A 2.000-mL aliquot of the Cu2 and Ni2solution is fed through an ion-exchange column that retains Ni2 .The Cu2 that passed through the column is treated with 25.00 mL0.04503 M EDTA. This solution required 21.76 mL of 0.02327 M Zn2for back titration. The Ni2 extracted from the column was treatedwitn 25.00 mL of 0.04503 M EDTA. How many milliliters of 0.02327 MZn2 is required for the back titration of the Ni2 solution?
