Question 17 For the acid-base indicator bromothymol blue, the protonated form, HBB, is yellow and the deprotonated form, BB, is blue. When both forms are present the indicator has a green color, the shade of green depends on the ratio of HBB:BB. Use the information below to calculate the concentration (10-6 M) of HBB for a green solution of bromothymol blue.
