Product Overview
Sodium carbonate AnalaR NORMAPUR® is a high-purity, ACS-grade reagent designed for demanding laboratory applications where precision and consistency are critical. This reagent-grade sodium carbonate meets the stringent specifications of the American Chemical Society (ACS) and European Pharmacopoeia (Ph. Eur.), ensuring minimal impurities and reliable performance in analytical procedures. Its fine, free-flowing powder form dissolves rapidly in water, providing a stable alkaline solution for titrations, pH adjustments, and buffer preparations. The AnalaR NORMAPUR® designation guarantees traceability and batch-to-batch uniformity, making it a trusted choice for quantitative analyses. With a molecular weight of 105.99 g/mol and a purity of ≥99.5%, this sodium carbonate delivers accurate stoichiometric reactions without interference from contaminants. Its hygroscopic nature requires proper storage to maintain integrity, but when handled correctly, it provides a cost-effective, high-performance alternative to lower-grade carbonates. The reagent’s compliance with international standards ensures compatibility with validated protocols in research and quality control environments.
FAQs
1. What is the difference between AnalaR NORMAPUR® and standard sodium carbonate?
AnalaR NORMAPUR® undergoes rigorous purification and testing to meet ACS and Ph. Eur. standards, ensuring lower trace metal content and higher consistency than technical or industrial grades. This makes it suitable for analytical applications where impurities could skew results.
2. Can this sodium carbonate be used for preparing standard solutions?
Yes, its ACS-grade purity and precise molecular weight (105.99 g/mol) make it ideal for preparing primary standard solutions in titrimetric analysis, provided proper drying and handling procedures are followed to account for moisture absorption.
3. How should this reagent be stored to maintain its purity?
Store in a tightly sealed container in a cool, dry place, away from moisture and acidic vapors. Use desiccants if long-term storage is required, as sodium carbonate is mildly hygroscopic and can absorb atmospheric CO₂ over time.
4. Is this product compatible with volumetric glassware for precise measurements?
The fine, uniform particle size and high solubility of this sodium carbonate allow for accurate weighing and dissolution, making it compatible with Class A volumetric glassware for precise concentration preparations.
5. What alternatives exist if Ph. Eur. compliance is not required?
For non-pharmacopeial applications, AR-grade or technical-grade sodium carbonate may suffice, though these typically contain higher levels of insoluble matter and heavy metals that could affect sensitive analyses.
