Product Overview
Fehling’s Solution B Indicator is a critical reagent used in biochemical and analytical laboratories for the detection of reducing sugars. This solution is part of the Fehling’s test, which is widely employed to distinguish between reducing and non-reducing sugars. The solution is composed of sodium potassium tartrate and sodium hydroxide, providing a stable alkaline medium that reacts with copper sulfate from Fehling’s Solution A to form a characteristic red precipitate in the presence of reducing sugars. The solution is prepared under stringent quality controls to ensure consistency and reliability in results. It is essential for experiments requiring precise sugar identification, such as those conducted in food science, biochemistry, and clinical diagnostics. The reagent is designed to be used in conjunction with Fehling’s Solution A, and its clear, colorless appearance ensures there is no interference with the visual detection of the reaction. Proper storage and handling are recommended to maintain its efficacy, as exposure to air or contaminants can alter its composition. This solution is a staple in laboratories due to its simplicity, cost-effectiveness, and accuracy in qualitative analysis.
FAQs
1. What is the shelf life of Fehling’s Solution B Indicator?
The shelf life of Fehling’s Solution B Indicator is typically 12 months from the date of manufacture when stored in a cool, dry place and kept tightly sealed. Over time, exposure to air can degrade the solution, so it is best to use it within the recommended period for accurate results.
2. Can Fehling’s Solution B Indicator be used alone for sugar testing?
No, Fehling’s Solution B Indicator must be used in combination with Fehling’s Solution A for the Fehling’s test. Solution A provides the copper sulfate necessary for the reaction, while Solution B creates the alkaline environment required for the test to work effectively.
3. How should Fehling’s Solution B Indicator be stored?
Fehling’s Solution B Indicator should be stored in a tightly sealed container, away from direct sunlight and moisture. It is best kept in a cool, dry place to prevent contamination or degradation of the solution over time.
4. Is Fehling’s Solution B Indicator hazardous?
Fehling’s Solution B Indicator contains sodium hydroxide, which is corrosive and can cause skin and eye irritation. It should be handled with care, using appropriate personal protective equipment such as gloves and goggles, and should be used in a well-ventilated area.
5. What is the difference between Fehling’s Solution A and Solution B?
Fehling’s Solution A contains copper sulfate, which provides the copper ions necessary for the reaction, while Fehling’s Solution B contains sodium potassium tartrate and sodium hydroxide, which create an alkaline medium. Both solutions are required for the Fehling’s test to detect reducing sugars.
