A 20.0 mL solution containing 0.250 M Ni2+ ion was titrated with 0.0500 M EDTA while the
system was buffered at pH=4.00.
Determine the volume of EDTA needed to reach the
equivalence point.
What is the free Ni2+ ion concentration ([Ni2+]) left in the solution at the
equivalence point?
The formation constant (Kf) for NiâEDTA complex is 1018.4.
