Bromothymol Blue 0.04% Indicator Solution 100ml

The Bromothymol Blue 0.04% Indicator Solution 100ml is a ready-to-use pH indicator solution, supplied in a convenient ethanol-based formulation for immediate use in laboratory and classroom settings. This solution provides clear and reliable colour changes, making it ideal for demonstrating acid-base reactions and pH variations in school science lessons.

Containing 0.04% bromothymol blue in ethanol and identified by CAS No: 76-59-5, this indicator transitions from yellow (acidic) through green (neutral) to blue (alkaline) within a pH range of approximately 6.0 to 7.6. Its distinct colour change around neutral pH makes it particularly useful for observing neutralisation reactions.

Pre-prepared for ease of use, this solution eliminates the need for mixing powders, ensuring consistent and accurate results in every experiment.
