(6 pts.) Potassium dichromate (Kucr.o.) and potassium permanganate (KMn 04) in H2SO4 1M They have overlapping absorption spectra. The KaCraOn has an absorption maximum at 440 nm. and KMnO has a maximum band at 545 nm. When a mixture containing dichromate (Cr20.," and permanganate (MnO) is analyzed in a cell with a path length of 1.00 cm, it is obtained the results shown in the table below. Calculate the concentrations molars of dichromate (Cr0% and permanganate (Mno) in the sample solution. 545nm 440nm 374 Ecset 9 Ecrao! EMNOT Shop 2.38x10 95 Asanm 0.712 A440nm 0.405
