Bromocresol purple is widely used as a pH indicator in various laboratory and industrial applications. It is particularly effective in the pH range of 5.2 to 6.8, where it transitions from yellow to purple. This makes it a valuable tool in titrations, especially for determining the endpoint in acid-base reactions. In microbiology, it is utilized in culture media to monitor pH changes, aiding in the identification and growth of specific microorganisms. Additionally, it is employed in biochemical assays to track enzymatic activities that alter pH levels. Its stability and distinct color change also make it suitable for educational purposes in teaching pH concepts and experimental techniques.
