EDTA binds metal ions to form complex ions (see 19.150),
Chapter 19, Problem 19.156(choose chapter or problem)
EDTA binds metal ions to form complex ions (see 19.150), so it is used to determine the concentrations of metal ions in solution: A 50.0-mL sample of 0.048 M Co2? is titrated with 0.050 M EDTA4. Find [Co2?] and [EDTA4] after (a) 25.0 mL and (b) 75.0 mL of EDTA4 are added (log Kf of CoEDTA2? 16.31). M
