Meaning
A dye used as an acid-base indicator.
Classification
Nouns denoting substances.
Examples
- Bromophenol blue is a commonly used acid-base indicator in chemistry labs due to its distinct color change between pH 3.0 and 4.6.
- The solution turned yellow as the pH increased, indicating the bromophenol blue had reached its endpoint as an acid-base indicator.
- In the experiment, bromophenol blue was added to the mixture as an acid-base indicator to track the pH changes.
- Bromophenol blue is often used in conjunction with other indicators to provide a broader pH range for acid-base titrations.
- The acid-base indicator bromophenol blue changed from yellow to blue as the pH of the solution decreased below 3.0.
