Item 23: Question In its protonated form, bromothymol blue has a molar absorptivity of 13800 M¹cm¹ at 435 nm. At the same wavelength, the deprotonated form of bromothymol blue has a molar absorptivity of 3410 M¹ cm ¹¹. If a solution contains 2.80 x 105 M protonated bromothymol blue and 5.00 x 10 5 M deprotonated bromothymol blue, what is the absorbance of the solution in a 1.00-cm sample cell at 435 nm? 0.228 0.557 0.785 1.34
