A solution contains 1.197 mg of CoSO4 (155.0 g/mol) per milliliter. Calculate a. the volume of 0.007840 M EDTA needed to titrate a 25.00-mL aliquot of this solution. Volume= mL [References] b. the volume of 0.006101 M Zn2+ needed to titrate the excess reagent after addition of 50.00 mL of 0.007840 M EDTA to a 25.00-mL aliquot of this solution. Volume = mL c. the volume of 0.007840 M EDTA needed to titrate the Zn2+ displaced by Co2+ following addition of an unmeasured excess of ZnY2 to a 25.00-mL aliquot of the CoSO4 solution. The reaction is Co2++ZnY2 CoY2+Zn2+ Volume= mL
