Bromothymol blue is a pH indicator that changes color depending on the acidity or basicity of a solution. It is commonly used in laboratory settings and educational demonstrations. The color change occurs in the pH range of about 6.0 (yellow) to 7.6 (blue), making it useful for determining whether a solution is acidic (pH < 6) or basic (pH > 7.6).

Key Properties of Bromothymol Blue:

• Color Change: Yellow in acidic solutions, green in neutral, and blue in basic solutions.
• pH Range: Effective between pH 6.0 and pH 7.6.
• Uses: Commonly used in titrations, to monitor CO2 levels in water (as in aquatic systems), and in various biochemical assays.

General Applications of Bromothymol Blue:

• Biological Experiments: Helps in measuring pH changes during respiration and photosynthesis.
• Water Quality Testing: Useful in assessing the pH of water samples.
