Astudent poured a solution of bromothymol blue (bmb) into three test tubes. (bmb turns yellow in the presence of co2.) then he placed an aquatic plant in two of the test tubes, as shown in the diagram (you will see the diagram when you are taking the test). he placed a stopper on each test tube and placed them all in the dark for two days. predict what change of color, if any, would occur in each of the test tubes. explain your answer. (2 points extra credit): describe what color change would occur in each tube, if any, if the experiment were done in the light. explain your answer.
