water sample is determined through a spectrophotometric method based on the reaction of phosphate ion with molybdate ion, by originating a yellow complex. Calibration standards (P1 to P5) are prepared as follows: different volumes of a 102.2 mgL1 phosphate solution are added to several 100 mL volumetric 1. The content of phosphate in a flasks. Then, 10 mL of diluted HCI, 10 mL of 1% molybdate ion solution, and 10 mL of 0.75% oxalic acid solution are added to every flask, and finally water is added up to the volumetric mark. Samples are prepared in the same way, adding different sample volumes instead of phosphate standard solution.

Application of Spectroscopy: 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 Fe3+ solution with a concentration of 7.50 x 10-4 M. You treat 15.0 mL of this reference with HNO, and excess KSCN to form a red complex, and dilute the reference to 55.0 mL. The diluted reference is placed in a cell with a 1.00-cm light path. You then take 15.0 mL of the well water, treat with HNO, and excess KSCN, and dilute to 100.0 mL. This diluted sample is placed in a variable pathlength cell. The absorbance of the reference and the sample solutions match when the pathlength is 1.91 cm. What is the concentration of iron in the well water? For each solution, the zero is set with a blank.
