Bromocresol green pH indicator solution is widely used in laboratories to determine the pH of various substances. It is particularly effective in the pH range of 3.8 to 5.4, where it transitions from yellow in acidic conditions to blue in alkaline conditions. This makes it a valuable tool in titrations, especially for weak acid-strong base reactions. In microbiology, it is employed to monitor pH changes in culture media, ensuring optimal conditions for microbial growth. Additionally, it is used in environmental testing to assess the acidity or alkalinity of water samples, aiding in pollution control and water quality management. Its clear color change provides a simple and reliable method for pH measurement in both educational and professional settings.
