Product Overview
NAPHTHOLBENZEIN Indicator grade is a high-performance synthetic dye designed for precise pH detection in laboratory titrations. This indicator-grade compound exhibits a distinct color transition at specific pH ranges, making it indispensable for analytical chemistry applications where accuracy is critical. The powdered form ensures easy dissolution and uniform distribution in aqueous solutions, providing consistent results across repeated experiments. Its stable chemical structure minimizes degradation over time, maintaining reliability even under varying storage conditions. The indicator’s sharp color change?typically from yellow to red?allows for clear endpoint visualization during acid-base titrations, reducing human error in measurements. Manufactured under stringent quality controls, this product meets laboratory standards for purity and performance, ensuring compatibility with standard titration protocols. Whether used in educational demonstrations or advanced research, NAPHTHOLBENZEIN delivers reproducible results, making it a trusted choice for chemists and technicians.
FAQs
1. What is the pH range where NAPHTHOLBENZEIN shows a color change?
NAPHTHOLBENZEIN typically transitions between pH 8.2 and 10.0, shifting from yellow to red as the solution becomes more alkaline.
2. Can this indicator be used in non-aqueous titrations?
While primarily designed for aqueous solutions, it may work in certain polar organic solvents, but calibration and compatibility should be verified beforehand.
3. How should NAPHTHOLBENZEIN be stored to maintain its shelf life?
Store in a cool, dry place away from direct sunlight and moisture, preferably in an airtight container to prevent oxidation or contamination.
4. Is this product compatible with automatic titrators?
Yes, its stable color transition makes it suitable for both manual and automated titration systems, provided the instrument is calibrated for this indicator.
5. Are there any safety precautions to consider when handling this indicator?
Wear gloves and protective eyewear, as the powder may cause irritation. Avoid inhalation and ensure proper ventilation during use.
