How many toothed ligands are not preferred in complexometric titrations? A. 6 gear B. 4 gear C. single gear D. two gear
Why do soft metals which tend to form stable aqueous complexes with soft ligands tend to be more toxic than hard metals?
Which of the following ligands would have the greatest affinity for Al3+? a) SH- b) F- c) NH3 d) Cl- Can you please explain How I would determine this even with other metals, does this have to do with the like things like each other, the soft acids like soft bases?
Why is the pH of the medium important for the formation of chelated complexes between metal ions and ligands? Choose the best answer: Select one: a. Because the ligands give rise to acid-base reactions that influence the stability of the chelate b. Because if the pH is not very acidic, the ligands do not protonate and the complex cannot form c. Because the pH of the medium is always important for any type of reaction. d. Because in the absence of pH there is no reaction of any kind
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.
A solution is prepared by mixing the two solutions together. The first solution is 150.0 mL and contains 30.78 mM Ti3+, 29.40 mM Ce3+, and 8.75 mM HCI. The second solution is 200.0 mL and contains 40.23 mM EDTA and 11.48 mM piperidine. Determine the concentration of free (non-complexed) metals when the two solutions are mixed.
Experimentally, it is found that the value of DO varies with the chemical nature of the ligand according to the spectrochemical series: S2− < Cl− < OH− ≈ RCO2− < H2O ≈ RS− < NH3 ≈ imidazole (the side chain of histidine) < CN− < CO. (a) Draw an energy level diagram like those in Fig. 10.41 showing the configuration of the d electrons on the metal ion in [Fe(OH2)6]3+ and [Fe(CN)6]3−.
1) Why are lanthanide complexes always weak field in nature , second and third d-transition metal complexes are nearly always strong field cases , and first d-transition series metal complexes exhibit both weak and strong field cases? 2) Sketch the structure for the [PtCl3(H2C=CH2)]- anion and describe the platinum(II)-ethene bonding.
Do ligand exchange to get PotassiumCopperOxalateDihydrate from Tetraamminecopper(II)sulfate, and do same to get ammonium iron(III)sulphate from PotassiumCopperOxalateDihydrate, and same to get carbonatotetraamminecobalt(III)nitrate from ammonium iron(III)sulphate and give a practical application of the final complex formed
Is there a way to tell which ligands are strong-field and which are weak-field, or is that just something I need to memorize?
