The apparent color of a solution corresponds to the wavelengths of visible light the solution transmits. Thus, a green transmits green light, and it absorbs red and blue light. The wavelength ranges corresponding to each color of light are approximate: red, 700-620 nm; orange, 620-590 nm ; yellow , 590-570 nm; green, 570-500 nm; violet, 450-400nm. You have drawn the absorption spectra for the solution containing 5.0, 6.7, and 7.5 mL of 2.0 X10^-2 M EN. Account for the color of each of these solutions on the basis of its lambda max.
