Product Overview
Fehling’s Solution A Indicator is a copper(II) sulfate-based reagent widely used in qualitative chemical analysis to detect the presence of reducing sugars. This solution is a critical component in Fehling’s test, where it reacts with aldehyde functional groups to form a characteristic red precipitate of copper(I) oxide. The high-purity grade ensures accurate and consistent results, making it a reliable choice for laboratory applications. The solution is prepared under controlled conditions to maintain stability and prevent contamination, ensuring long shelf life when stored properly. Its deep blue color indicates the presence of copper ions, which are essential for the redox reaction during testing. Fehling’s Solution A is commonly paired with Fehling’s Solution B (alkaline sodium potassium tartrate) to perform the complete test. The solution is non-toxic and safe for routine lab use, provided standard handling precautions are followed. Its compatibility with various lab glassware and equipment makes it a versatile reagent for both educational and research environments. Proper storage in a cool, dry place away from direct sunlight is recommended to maintain its efficacy over time.
FAQs
1.
What is the shelf life of Fehling’s Solution A Indicator?
The shelf life is typically 12-24 months when stored in a tightly sealed container at room temperature, away from light and moisture. 2.
Can Fehling’s Solution A be used alone for sugar detection?
No, it must be mixed with Fehling’s Solution B (alkaline tartrate) in equal volumes before use to create the complete Fehling’s reagent for accurate testing. 3.
Is this solution compatible with plastic containers?
While it can be stored in high-quality plastic containers, glass is preferred to prevent potential leaching or reactions with certain plastics over time. 4.
What precautions should be taken while handling Fehling’s Solution A?
Wear protective gloves and goggles, as the solution contains copper sulfate, which can be harmful if ingested or in contact with skin. 5.
How should I dispose of expired or unused Fehling’s Solution A?
Follow local laboratory waste disposal guidelines, as it contains copper compounds that may require special handling as chemical waste.
