Bromothymol Blue is a pH indicator dye that changes color according to the acidity or alkalinity of a solution. It turns yellow in acidic environments (pH < 6.0), becomes green at neutral pH levels (approximately 7.0), and appears blue in basic conditions (pH > 7.6). Frequently utilized in scientific experiments, it provides a visual indication of pH changes, making it particularly useful in studies related to photosynthesis and respiration.
