Calculate the total spin of this complex ion [NiCl6] 4-

The MO scheme shown below is for the complex [Cr(NH3)6]*. This high spin compound shows an absorption feature at 510 nm in its UV-visible spectrum. 6L M ML6 4p 4s 3d t2g Lo Op 2.1 What is the geometry of this complex?

[Co(H2O)6]2+(aq)   +   4 Cl- (aq)   <=====>   [CoCl4]-2 (aq)   +   6 H2O (l)   The absorbance of the blue ion is easily measured and a calibration curve for this species gives the line:  A = 58.2 C.  Assume that the initial concentration of [Co(H2O)6]2+ is 0.0500 M and the initial concentration of Cl- is 0.200 M.  If the absorbance of [CoCl4]-2 is 0.856, calculate the equilibrium constant for the reaction.

A hypothetical metal M forms the following complexes with the generalized ligands X, Y, and Z:   Complex ion Observed color [M(X)6]3+ green [M(Y)6]3+ blue [M(Z)6]3+ yellow Order these ligands according to their ability to split d orbitals. In other words, set up a spectrochemical series, from strongest to weakest ligand field strength. Rank from strongest to weakest ligand field strength.    -X -Z -Y
