Bromothymol Blue (pH Indicator) 5g

The Bromothymol Blue 5g is a versatile and widely used pH indicator dye, ideal for educational and laboratory applications. Supplied in a convenient 5g quantity, this indicator is perfect for demonstrating pH changes clearly and effectively in school science lessons.

Identified by CAS No: 76-59-5, bromothymol blue is commonly used to indicate pH changes in the range of approximately pH 6.0 to 7.6, transitioning from yellow (acidic) through green (neutral) to blue (alkaline). This makes it particularly useful for observing neutralisation reactions and studying changes around neutral pH.

Reliable and easy to use, this indicator provides clear visual results, making it an essential tool for engaging classroom demonstrations and practical investigations.
