Product Description:
Bromothymol blue is widely used as a pH indicator in various scientific and industrial applications. It is particularly effective in determining the acidity or alkalinity of a solution, with a color change from yellow in acidic conditions (pH below 6.0) to blue in basic conditions (pH above 7.6). In educational settings, it is commonly employed in laboratory experiments to visually demonstrate pH changes during titrations or chemical reactions. In microbiology, it is used in culture media to monitor pH shifts caused by microbial activity. Additionally, bromothymol blue is utilized in environmental testing to assess the pH of water samples, helping to evaluate water quality. Its ability to provide a clear visual indication of pH makes it a valuable tool in both research and practical applications.
