Iron(II) is determined spectrophotometrically by reacting with 1,10 -phenanthroline to produce a complex that absorbs strongly at 510 nm. A stock standard iron(II) solution is prepared by dissolving 0.0702 g ferrous ammonium sulfate, Fe(NH4)2 SO4 ·6 H2 O, in water in a 1-L volumetric flask, adding 2.5 mL H2 SO4, and diluting to volume. A series of working standards is prepared by transferring 1.00-, 2.00-, 5.00-, and 10.00-mL aliquots of the stock solution to separate 100-mL volumetric flasks a

SOLVED: Calculate the molarity of the Fe(o-phenanthroline)32 in each standard solution. Note that all the Fe2 in the standard solution is converted to Fe(o-phenanthroline)32 according to the following reaction:1 Fe2 3 o-phenanthroline â†’ 1 Fe(o-phenanthroline)32 Therefore, all moles of Fe2 have been converted to Fe(o-phenanthroline)32 in a one-to-one mole ratio, and the molarity of the iron (II) present as a reactant will equal the molarity of the Fe(o-phenanthroline)32 formed as a pro

SOLVED: The complex formed between Cu(I) and 1,10-phenanthroline has a molar absorptivity of 7000 L cm^2 mol^-1 at 435 nm, the wavelength of maximum absorption. Calculate:(a) the absorbance of a 6.17 x 10^-5 M solution of the complex when measured in a 1.00-cm cell at 435 nm.(b) the percent transmittance of the solution in (a).(c) the concentration of a solution that in a 5.00-cm cell has the same absorbance as the solution in (a).(d) the path length through a 3.13 x 10^-5 M solution of the comp
