Zinc(II) and the ligand L form a 1:1 complex that absorbs strongly at 600 nm. As long as the molar concentration of L exceeds that of zinc(II) by a factor of 5, the absorbance depends only on the cation concentration. Neither zinc(II) nor L absorbs at 600 nm. A solution that is 1.59 10-4 M in zinc(II) and 1.00 10-3 M in L has an absorbance of 0.352 in a 1.00-cm cell at 600 nm. Calculate (a) the percent transmittance of this solution. (b) the percent transmittance of this solution in a 2.50-cm cell. (c) the molar absorptivity of the complex.

Explain why the complex [Fe(H2O)6]3+ has Do = 14,000 cm-1, while [Fe(H2O)6]2+ has Do = 9,350 cm-1.
Consider the solvatochromic complex, [Mo(bipy)(CO)4]. The complex has a MLCT peak in the UV-vis spectrum. This peak is at 533 nm in acetonitrile solvent and at 584 nm in benzene solvent.

Scott test is one of the methods used for screening for Cocaine in Forensic Chemistry. The multi step method consists of a) reacting the sample drug with cobaltous thiocyanate b) dissolving of the formed precipitate by adding HCl and c) extraction of coordination compound with Chloroform d) measurement of absorbance of extracted coordination compound at 627 nm All the reactions in this multistep method are not fully understood. However, it was determined that there are 2 moles of cocaine in coordination compound measured in last step. If coordination compound is represented as “Scott” coordination compound, which of the following is correct “stoichiometric” factor to get mass of cocaine from mass of measured complex ? a.g (Scott coordination cpd) * MM (Scott coordination cpd) MM (cocaine) b.g (Scott coordination cpd) * 2 *MM (Scott coordination cpd) MM…
