SOLVED: A standard solution was put through appropriate dilutions to give the concentrations of iron shown next. The iron(II)-1,10 phenanthroline complex was then formed in 25.0 mL aliquots of these solutions, following which each was diluted to 50.0 mL. The following absorbances (1.00 cm cell) were recorded at 510 nm: (Use spreadsheet like "Excel".)Fe(II) concentration; ppm 4.00Asio0.760 0.390 0.63010.016.024.00.950320T26o40.01.580Plot a calibration curve from these data.(b) Use the method of l

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
