question 19

Essay

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 of HBB and BB⁻ for a green solution of bromothymol blue.
