Did You Know?
Bromothymol blue is best known for its sharp color change between pH 6.0 and 7.6, making it an excellent indicator for studying neutralization reactions and biological systems. It is commonly used in photosynthesis experiments to visually track carbon dioxide uptake, as well as in aquatic science to assess water quality. Because its transition range closely aligns with neutral pH, bromothymol blue remains one of the most effective indicators for demonstrating real-world chemical equilibria.
