Four solutions were prepared by dissolving 4.00 × 10-4. 3.00 × 10-4. 2.00×10-4 and 1.00 x 10-4 moles of K2Cr2O2 in water and diluting to 1.00 L with a pH 5.60 buffer. Derive theoretical absorbance values (1.00-cm cells) for each solution and plot the data for
(a) 345 nm,
(b) 370 nm. and
(c) 400 nm.
