Product Description:
Xylenol Blue is widely used as a pH indicator in various chemical and biological applications. It is particularly useful in titration experiments to determine the endpoint of acid-base reactions, as it transitions from yellow to blue within the pH range of 8.0 to 9.6. In microbiology, it serves as a component in culture media to monitor pH changes during bacterial growth. Additionally, it is employed in analytical chemistry for detecting metal ions, such as aluminum and zinc, due to its ability to form colored complexes. Xylenol Blue is also utilized in environmental testing to assess water quality by measuring pH levels in aquatic systems. Its versatility and distinct color change make it a valuable tool in both laboratory and industrial settings.
