A solution of [Ni(H2O)6]2+ is green and paramagnetic (µ = 2.90 BM), whereas a solution of [Ni(CN)4]2- is colorless and diamagnetic.

Suggest a qualitative explanation for these observations. Include diagrams showing the molecular geometry for each complex. you may draw crystal field diagrams for both molecules to explain the magnetic behavior of these complexes. Be sure to suggest a reason why [Ni(H2O)6]2+ is green and [Ni(CN)4]2- is colorless.

Provide a reasonable explanation for the following experimental observations. a) The wavelength of the absorption maximum in the UV/vis spectra of Cr(III) complexes decreases in the order [CrCl6]3-, [Cr(NH3)6]3+, [Cr(CN)6]3-. b) Low spin Fe(III) complexes have stronger d-d transitions (are more intensely colored) than the corresponding high spin complexes. c) The initial rate of Cl- substitution is 108 times faster for [Fe(H2O)6]2+ (μeff = 5.9 μB) than for [Ru(H2O)6]2+ (μeff = 0 μB) and is independent of the concentration of...

I have provided the information for the lab below. I want to see the chemical reactions that take place during each step of the experiment. So in the procedures when a chemical was added i would like to see what the products and byproducts that were formed. I also want to see one over all reaction for this experiment to just get an overview of what exactly is happening during the experiment. Thank you:) Part B: Synthesis of [Co(NH3)5Cl]Cl2 Objective:...
