Procedure 1.00,2.00,3.00,4.00,5.00 ml of the standard Fe2+ solution was pipetted into separate 100mL volumetric flasks. The flasks were then filled with 5mL of toxic water, 5ml of 2M sodium acetate, and 4mL of 3M NH2OH. The flasks were then diluted with DI water to the 100mL mark, mixed, and let sit for 5 minutes. After 5 minutes, the absorption spectrum of the FeLn²+ for each of the Fe2+ solutions was measured using a spectrophotometer The absorbance was recorded at a peak wavelength of 510. | Results and Discussion Vol Fe Wavelength (nm) Abs Concentration 1 516 0.022 2 521 0.031 3 522 0.041 4 522 0.051 5 513 0.024 о What was the concentration?
