A 25.0 mL aliquot of 0.0430 0.0430 M EDTA EDTA was added to a 56.0 56.0 mL solution containing an unknown concentration of V 3 + V3+ . All of the V 3 + V3+ present in the solution formed a complex with EDTA EDTA , leaving an excess of EDTA EDTA in solution. This solution was back-titrated with a 0.0490 0.0490 M Ga 3 + Ga3+ solution until all of the EDTA EDTA reacted, requiring 13.0 13.0 mL of the Ga 3 + Ga3+ solution. What was the original concentration of the V 3 + V3+ solution?
