Xylenol Orange sodium salt NEW

Xylenol Orange sodium salt is a chemical compound commonly used as a pH indicator and complexometric reagent in various analytical chemistry applications. Here are its main uses:

1. pH Indicator:
   Xylenol Orange is a pH-sensitive dye that changes color over a pH range of approximately 3.0 to 8.0. It transitions from yellow at low pH to orange or red at higher pH levels. This makes it useful in titrations or as a visual indicator for detecting pH changes in a solution.

2. Complexometric Titrations:
   Xylenol Orange is also used in metal ion titrations, particularly for determining the concentration of metal ions like copper, iron, and zinc. It can form colored complexes with metal ions, allowing for visual detection of endpoint changes in the titration.

3. Trace Metal Detection:
   It can be used in the detection of trace amounts of metal ions in samples, especially in environmental analysis, as the complex formed with metal ions often has a distinct color that can be measured using spectrophotometry.

4. Fluorescence Studies:
   In some cases, Xylenol Orange can be used in fluorescence spectroscopy due to its ability to fluoresce when bound to metal ions, offering an additional method for detecting and quantifying metals in solutions.

Due to its versatile applications, Xylenol Orange sodium salt is commonly found in laboratory settings, particularly in chemical analysis and environmental monitoring.
