The citrate ion is a tridentate ligand that forms a strong complex with ferric ion: Fe^3+ + 2Cit^3- <=> Fe(Cit)2^3- A metal ion buffer solution was prepared by adding 2.5g of Na3Cit.2H2O (MW = 294.1) and 1 g of Fe(NO3)3.9H2O (MW=404.01) to a 500ml volumetric flask. The flask was filled to the mark and mixed throughly after the reagents dissolved. The pFe = 18.56, Calculate Kf.
Question: Although both nitrogen and phosphorous take place in Group VA, in complex formation ammonia acts as sigma-donor while PR3 is both sigma–donor and pi-acceptor. In the light of this explanation, show the sigma and pi interactions in [Co(PR3)6]2+ according to MO theory. What makes PR3 a different ligand than ammonia? Do I need to replace t2g orbitals in my diagram? How can I show PR3 ligands using d orbitals?

A sample contains Pb2+, Mg2+ and Zn2+. 0.4085 g of the sample is weighed and dissolved. Once dissolved it is with cyanide to form a complex and mask the zinc (Zn2++ 4 CN-→ Zn (CN)4 2-). The Pb2+ and Mg2+ in the solution are titrated with 42.22 mL of EDTA 0.02604 M. Then the Pb complex is treated with another organic ligand that masks Pb and releases EDTA, which is titrated with 19.35 mL of a Mg2+ 0.007657 M solution. For finalize formaldehyde is added to unmask the Zn2+(Zn (CN)4 2- + 4 HCHO + 4 H2O → Zn2+ + 4 HOCH2CN + 4 OH-). The liberated zinc is titrated with EDTA 0.02064 M consuming 28.63 mL. (Data: Pat Pb, 207.22; Pat Mg, 24.31; Pat Zn, 65.4). Find the percentage of the three metals in the sample.
