Hg2+ forms a complex with diphenylcarbazone (1:1). The complex absorbs light at 550 nm with an of 19425Lmol1cm1. a. What concentration of Mercuric Diphenylcarbazone (HgL2+) is required to achieve an absorbance value of 1.00Au in a 1.00cm cuvette. b. This complex is disrupted (at pH 1-3) by chloride (Cl1). The disruption of the complex by chloride is accompanied by a drop in absorbance. The reaction is as follows: HgL2++2ClHgCl2+L. This reaction is very favorable (proceeds to completion) and the "decolorization" of the solution can be used as a measurement of Chloride in water samples. Hg(NO3)2 and diphenylcarbazone are added to a 5.00mL volumetric flask in sufficient quantity so that upon dilution to 5.00mL the absorbance would be (in the absence of chloride) 1.00Au. Before dilution of the added mixture a 0.0500mL aliquot of a drinking water sample is added, and then the sample is then diluted to 5.00mL. The absorbance is measured at 0.728Au. What is the concentration of chloride in the drinking water sample (be sure to correct for dilution)
