Fe 2+ + 3(phen) -> Fe(phen) 2+ 1ppm= 1 mg/L Calculate molar absorptivity from the slope. (Note 4) b=1 cm A= .147 c= 1 ppm

Fe²⁺ + 3(phen) -> Fe(phen)²⁺

1ppm= 1 mg/L

Calculate molar absorptivity from the slope. (Note 4)

b=1 cm

A= .147

c= 1 ppm

Note 4. Beers Law: -log%T = A = bc where = molar absorptivity (units of M-1 cm-1), b is the pathlength and c is molar concentration. For a fitted calibration curve the slope is b when c is molarity.
