Bromophenol Blue (pH Indicator) 5g

The Bromophenol Blue 5g is a reliable and widely used pH indicator dye, ideal for educational and laboratory applications. Supplied in a convenient 5g quantity, this indicator provides clear and distinct colour changes, making it perfect for demonstrating acid-base reactions in school science lessons.

Identified by CAS No: 115-39-9, bromophenol blue is commonly used to indicate pH changes in the range of approximately pH 3.0 to 4.6, transitioning from yellow (acidic) to blue-purple (alkaline). Its sharp and visible colour change makes it especially useful for titrations and analytical experiments.

Easy to use and highly effective, this indicator is a valuable addition to any school laboratory, supporting accurate and engaging practical work.
