Product Overview
Sodium hydroxide, 50% w/w aqueous solution, is a highly concentrated, corrosive alkaline reagent widely used in laboratory settings for its strong basic properties. This reagent-grade solution ensures high purity and consistency, making it suitable for precise applications such as pH adjustment, acid neutralization, and organic synthesis reactions. The solution is prepared by dissolving sodium hydroxide pellets in deionized water to achieve a 50% concentration by weight, providing a stable and ready-to-use form for various chemical processes. Its high reactivity necessitates careful handling, and it should be stored in tightly sealed containers to prevent absorption of atmospheric carbon dioxide, which can degrade its potency. The solution is compatible with glass and certain plastic labware, though prolonged exposure may cause corrosion. For optimal performance, it is recommended to use this solution in well-ventilated areas with appropriate personal protective equipment, including gloves and goggles, to minimize exposure risks.
FAQs
1. What is the shelf life of sodium hydroxide 50% solution?
The shelf life is approximately 12 months when stored in a tightly sealed container at room temperature, away from moisture and direct sunlight.
2. Can this solution be used for cleaning glassware?
Yes, it is effective for cleaning glassware due to its strong alkaline nature, but it should be thoroughly rinsed afterward to avoid residue.
3. Is this solution compatible with plastic containers?
It can be stored in HDPE or PP containers, but prolonged contact may cause degradation, so glass is preferred for long-term storage.
4. How should I dispose of unused sodium hydroxide solution?
Neutralize with a dilute acid like hydrochloric acid before disposal, following local environmental regulations for chemical waste.
5. What precautions should be taken while handling this solution?
Wear chemical-resistant gloves, goggles, and a lab coat. Avoid inhalation and skin contact, and use in a fume hood or well-ventilated area.
