WebAfter your design is approved by your teacher, use the supplies available to set up your experiment. NOTE: To determine the amount of bromothymol solution that should be used in each of your test tubes pour a filled test tube into the graduate cylinder. Fill a 500 ml flask with all of the bromothymol blue that you will need to turn yellow. WebHow BTB works: BTB stands for “bromothymol blue” which is colorimetric indicator for solution pH. In Carbon TIME we use BTB to detect CO2. When CO2 dissolves in water, it forms a weak acid (carbonic acid), which makes the pH of pure water as low as 5.5. In solutions with pH > 7.1 BTB is blue. In solutions with pH < 6.4 BTB is yellow.
