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.
