Question
USE THE DATA BELOW ON MOLAR ABSORPTIVITIES FOR THE TWO PRINCIPAL SPECIES IN A SOLUTION OF POTASSIUM DICHROMATE. Four solutions were prepared by dissolving 3.50 x 10^-4 , 3.00 x 10^-4, 2.50 x 10^-4, and 2.00 x 10^-4 moles of K2Cr2O7 in water and diluting to 1.0 L with a pH of 5.55 buffer. Derive theoretical absorbance values using a 1.00-cm cells for each solution and plot the data for (a) 345 nm (b) 370 nm, and (c) 400 nm.
