Product Overview
Sulfuric acid (H₂SO₄), 50% AR-grade, is a highly concentrated mineral acid widely used in laboratory settings for its strong acidic properties and versatility. This analytical reagent (AR) grade ensures minimal impurities, making it suitable for precise chemical reactions, titrations, and sample preparations. The 50% concentration provides a balanced strength for controlled experiments without excessive dilution requirements. Its hygroscopic nature demands careful handling, and it is commonly stored in high-density polyethylene (HDPE) containers to prevent corrosion. The acid’s ability to donate protons makes it indispensable in acid-base reactions, while its dehydrating properties are leveraged in organic synthesis. Due to its corrosive nature, proper safety measures, including the use of fume hoods and protective gear, are essential when handling this reagent. The 5 L pack size is ideal for laboratories with moderate to high usage, ensuring a steady supply without frequent reordering.
FAQs
1. What is the shelf life of 50% AR sulfuric acid?
When stored in a tightly sealed container away from moisture and direct sunlight, 50% AR sulfuric acid remains stable for up to 2 years.
2. Is this sulfuric acid compatible with glass containers?
While short-term storage in glass is possible, prolonged exposure can cause corrosion. HDPE or PTFE containers are recommended for long-term storage.
3. Can this acid be used for battery electrolyte preparation?
This 50% concentration is not ideal for battery use; higher concentrations (typically 98%) are required for lead-acid battery electrolytes.
4. What safety precautions should be taken while handling this acid?
Always wear acid-resistant gloves, goggles, and a lab coat. Work in a fume hood to avoid inhalation of fumes, and neutralize spills with sodium bicarbonate.
5. How does AR grade differ from LR grade sulfuric acid?
AR (Analytical Reagent) grade has stricter purity standards and fewer impurities compared to LR (Laboratory Reagent) grade, making it more reliable for sensitive analyses.
