WebBromthymol blue is used as an indicator for the presence of CO2 in solution. When CO2 dissolves in water, carbonic acid is formed. A bromthymol blue solution, acidified to pH 6.0 by the addition of carbon dioxide produces a yellow color. The blue color is restored when the CO2 is removed and the pH becomes higher than 7.6. WebHow BTB works: BTB stands for “bromothymol blue” which is colorimetric indicator for solution pH. In Carbon TIME we use BTB to detect CO2.
