A 20 ml aliquot of drinking water containing Fe(II) and Fe (III) is treated with hydroquinone to reduce all dissolved iron to Fe(II),0- phenanthroline is added and the aliquot is diluted to 50 ml and the absorbance in a 2.00 cm cell is 0.085 at 510 nm. Calculate the iron content of the water as ppm? ε = 1.11 x104 L/mol cm
