Product Overview
Sodium pyrophosphate decahydrate (97%+ purity) is a high-quality laboratory reagent widely used for its exceptional buffering and chelating capabilities. This crystalline powder is highly soluble in water, making it ideal for applications requiring precise pH control and metal ion sequestration. Its stable chemical structure ensures consistent performance in various experimental conditions, while the decahydrate form provides enhanced solubility compared to anhydrous variants. The reagent-grade purity guarantees minimal impurities, reducing the risk of contamination in sensitive procedures. This compound is particularly valued for its ability to form stable complexes with calcium, magnesium, and other divalent cations, preventing precipitation in solutions. The product is packaged in airtight containers to maintain its integrity during storage and transportation. Each batch undergoes rigorous quality control to ensure compliance with laboratory standards, making it a reliable choice for demanding research environments.
FAQs
1. What is the solubility of sodium pyrophosphate decahydrate in water?
Sodium pyrophosphate decahydrate is highly soluble in water, with a solubility of approximately 65 g/100 mL at 20°C, forming a clear, colorless solution.
2. Can this compound be used as a food additive?
While this laboratory-grade product meets high purity standards, it is not specifically certified for food applications. Food-grade sodium pyrophosphate would be required for culinary or food processing uses.
3. How should sodium pyrophosphate decahydrate be stored for long-term use?
Store in a cool, dry place in tightly sealed containers to prevent moisture absorption. Keep away from incompatible substances like strong acids or oxidizing agents.
4. What is the difference between sodium pyrophosphate decahydrate and anhydrous sodium pyrophosphate?
The decahydrate form contains 10 water molecules per formula unit, making it more soluble and easier to dissolve compared to the anhydrous version, which requires more energy to dissolve.
5. Is this product compatible with common laboratory glassware?
Yes, sodium pyrophosphate decahydrate is compatible with standard borosilicate glassware and most plastic labware, though prolonged contact with some metals should be avoided.
