description Product Description
Xylenol Blue is widely used as a pH indicator in various chemical and biological applications. It is particularly useful in titrations to determine the acidity or alkalinity of a solution, transitioning from yellow to blue as the pH changes from acidic to basic. In microbiology, it serves as a pH indicator in culture media, helping to monitor the growth conditions of microorganisms. Additionally, Xylenol Blue is employed in analytical chemistry for complexometric titrations, especially in the determination of metal ions like calcium and magnesium. Its ability to form distinct color changes makes it a valuable tool in laboratory settings for accurate pH measurement and chemical analysis.
