Consider the possibility of applying the Bouguer-Lambert-Beer equation for hydrosols of iron hydroxide, using data on the attenuation of monochromatic light by these disperse systems:
Sol concentration, % (wt.) 0.20 0.10 0.08 0.04 0.02
Layer thickness, cm 2.5 2.5 2.5 5.0 5.0
Share of transmitted light, % 1.49 11.8 18.3 18.2 43.0
Determine what proportion of light will be scattered by a 0.02% sol in a 30 mm cuvette.
