Bromothymol blue turns to bromothymol yellow in the presence of carbon dioxide. When the carbon dioxide is removed, the solution will return to a blue color. Two green water plants were placed in separate test tubes, each containing water and bromothymol yellow. Both test tubes were corked. One tube was placed in the light, the other in the dark.
