Bromothymol blue is a pH indicator dye. It exhibits a color change from yellow in acidic solutions to blue in alkaline solutions, with a transition range of pH 6.0 to 7.6. This makes it useful for determining the pH of various solutions, including biological fluids, water samples, and chemical reactions

Color: Dark green to blue (solid powder); changes to yellow, green, or blue in solution depending on pH.

Material: Bromothymol Blue (C₂₇H₂₈Br₂O₅S)

Usage:

  • pH indicator for acid-base titrations and chemical experiments.
  • Carbon dioxide detection in biological processes.
  • Demonstrating pH changes in educational settings.

How to use:

  • Solution Preparation: Dissolve a small amount of Bromothymol Blue powder in ethanol or water to make an indicator solution.
  • Application: Add 1-2 drops of the solution to the sample being tested.
  • Color Change: Observe the color change to determine pH:
    – pH < 6.0: Yellow
    – pH 6.07.6: Green
    – pH > 7.6: Blue.
  • Storage: Store the powder in a cool, dry place in a tightly sealed container. Keep away from direct sunlight.

Application:

  • Laboratory: Acid-base titrations and pH measurement.
  • Biological Studies: Carbon dioxide monitoring in respiratory and photosynthesis experiments.
  • Educational: Teaching acid-base chemistry.
  • Chemical Analysis: Used in industrial and academic pH testing applications.
