Product Overview
Sodium carbonate, also known as washing soda, is a highly versatile inorganic compound with a purity of 98%, making it ideal for laboratory applications requiring consistent and reliable results. This white, odorless powder is hygroscopic and soluble in water, forming an alkaline solution that is widely used in chemical reactions, pH regulation, and as a buffering agent. Its strong basic nature allows it to neutralize acids effectively, making it a staple in titration experiments and synthesis processes. The high purity ensures minimal impurities, reducing the risk of unwanted side reactions in sensitive procedures. Sodium carbonate is stable under normal conditions but should be stored in a cool, dry place to prevent moisture absorption, which can alter its concentration. Whether used in qualitative analysis, cleaning glassware, or preparing standard solutions, this reagent delivers consistent performance, making it a trusted choice for researchers and educators alike.
FAQs
1. What is the shelf life of sodium carbonate, 98%?
When stored in a tightly sealed container away from moisture and direct sunlight, sodium carbonate retains its purity for up to 2–3 years. Always check for clumping before use, as exposure to humidity can affect its properties.
2. Can this sodium carbonate be used for food-grade applications?
This product is lab-grade (98% pure) and not certified for food or pharmaceutical use. For food-grade applications, ensure you source a product labeled explicitly for such purposes.
3. How does sodium carbonate differ from sodium bicarbonate?
Sodium carbonate (Na₂CO₃) is a stronger base with a higher pH (around 11 in solution), while sodium bicarbonate (NaHCO₃) is milder (pH ~8). Sodium carbonate is often used for more aggressive pH adjustments, whereas bicarbonate is preferred for gentler reactions.
4. Is this product compatible with plastic containers for storage?
While sodium carbonate itself doesn’t react with most plastics, prolonged storage in non-airtight plastic containers may lead to moisture absorption. Glass or HDPE containers with tight seals are recommended for long-term storage.
5. What safety precautions should be taken when handling sodium carbonate?
Wear gloves, goggles, and a lab coat to avoid skin and eye irritation. In case of contact, rinse thoroughly with water. Avoid inhaling dust, and work in a well-ventilated area or under a fume hood if handling large quantities.
