The pH indicator bromothymol blue turns yellow when CO2 gas is added to a
solution and blue when CO2 is removed from a solution. In an experiment that
tests how the intensity of light affects the rate of photosynthesis by algae,
how would bromothymol blue be used?
O
A. To estimate the temperature at which a solution containing algae
and the indicator turns blue under different intensities of light
O
B. To count the number of air bubbles in a solution containing algae
and the indicator when it turns yellow under different intensities of
light
O
C. To measure the volume of a solution containing algae and the
indicator when it turns yellow under different intensities of light
O
D. To determine how long it takes a solution containing algae and the
indicator to turn blue under different intensities of light
