Let's pretend you are a scientist for the Environmental Protection Agency (EPA) and need to test a water sample for iron. You generate a calibration curve and find the Beer's law slope for the Fe-phenanthroline complex is 0.215 L/mg Fe. The absorbance of the diluted unknown solution prepared in accordance with the instructions in this exercise is found to be 0.471. What is the concentration of the original unknown solution? 2.19 mg/L 21.9 mg/L

When the Ti3+ ion is complexed by ligands X (a neutral molecule) and Y" (an anion) it gives octahedral species of the type [TIX)6)3+ and [Ti(Y)6)³, respectively, which have two different colours. The complex containing ligand X shows a single absorbance in the visible region with a peak maximum at 520 nm, while that containing Y has a peak maximum at 580 nm. Which of the two ligands produces the higher crystal field splitting energy (CFSE) for Cu2+? O a. The crystal field splitting is not caused by the ligand as one complex is a cation and one is an anion O b. The CFSES for the two complexes are the same O. Ligand X produces the higher CFSE O d. Ligand Y produces the higher CFSE
