Bromothymol Blue is a pH indicator commonly used in laboratories and educational settings. It changes color based on the acidity or alkalinity of a solution, turning yellow in acidic conditions (pH below 6.0) and blue in basic conditions (pH above 7.6). This property makes it useful for experiments involving acids and bases. In addition to its role as a pH indicator, Bromothymol Blue is also used in biological applications, such as monitoring cellular respiration and photosynthesis. Its ability to indicate changes in pH helps scientists and students visualize chemical reactions and understand fundamental concepts in chemistry.
