A 25.0 mL aliquot of 0.0700 M EDTA was added to a 32.0 mL solution containing an unknown concentration of V3+. All of the V3+ present in the solution formed a complex with EDTA, leaving an excess of EDTA in solution. This solution was back- titrated with a 0.0380 M Ga³+ solution until all of the EDTA reacted, requiring 15.0 mL of the Ga³+ solution. What was the original concentration of the V³+ solution? [V³*] = M

A 0.6006-g sample of Ni/Cu condenser tubing was dissolved in acid and diluted to 100 mL in a volumetric flask. Titration of both ions in a 25.0ml aliquot of this solution required 45.81 mL of 0.052285M EDTA. Mercaptoacetic acid and NH3 were then introduced; production of the Cu complex with the former resulted in the release of an equivalent amount of EDTA, which required 22.85ml titration with 0.07238M Mg2+.
