Bromothymol blue (BTB) is a chemical indicator for carbon dioxide (CO2). In the presence of carbon dioxide (CO2), BTB turns from blue to yellow. An aquatic plant was placed into two test tubes containing BTB, and the test tubes were closed with a stopper. Then, one test tube was placed in the dark, and the other test tube was placed in direct sunlight. The test tube in sunlight stayed blue indicating no CO2 was present, while the test tube in the dark changed to yellow. Which statement best explains why the solution in the test tube placed in the dark changed to yellow?
