The ph indicator bromothymol blue turns yellow when co, gas is added to a
solution and blue when co, 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 count the number of air bubbles in a solution containing algae
and the indicator when it turns yellow under different intensities of
light
o
b. to estimate the temperature at which a solution containing algae
and the indicator turns blue 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
