You wish to measure the iron content of the well water on the new property you are about to buy. you prepare a reference standard solution with a concentration of you treat of this reference with and excess to form a red complex and dilute the reference to the diluted reference is placed in a cell with a 1.00‑cm light path. you then take of the well water, treat with and excess and dilute to this diluted sample is placed in a variable pathlength cell. the absorbance of the reference and the sample solutions match when the pathlength is what is the concentration of iron in the well water? for each solution, the zero is set with a blank.
