When species combine to produce a coordination complex, the equilibrium constant for the reaction is called is the formation constant, Kf. For example, the iron(II) ion, Fe2+, can combine with the cyanide ion, CN−, to form the complex [Fe(CN)6]4−according to the equation Fe2+(aq)+6CN−(aq)⇌[Fe(CN)6]4−(aq) where Kf=4.21×1045. The average human body contains 5.60 L of blood with a Fe2+ concentration of 1.80×10−5 M . If a person ingests 8.00 mL of 18.0 mM NaCN, what percentage of iron(II) in the blood would...
