Sodium chloride, commonly known as table salt, is a compound composed of sodium and chlorine ions in a 1:1 ratio. Lab grade sodium chloride typically refers to a purer form of the compound, suitable for laboratory use. Here are some features of lab-grade sodium chloride:
- Chemical Formula: NaCl
- Appearance: Typically white crystalline solid.
- Purity: Lab-grade sodium chloride is typically highly purified to remove impurities that might interfere with experimental results.
- Solubility: Highly soluble in water, forming a clear, colorless solution.
- Density: The density of sodium chloride depends on the form and purity, but typically around 2.16 g/cm³.
- Melting Point: Sodium chloride has a high melting point of 801 °C (1474 °F), making it suitable for various high-temperature applications.
- Boiling Point: Its boiling point is 1413 °C (2575.4 °F).
- Stability: It is stable under normal conditions.
- Hygroscopicity: Sodium chloride is hygroscopic, meaning it can absorb moisture from the atmosphere.
- Applications: It is widely used in laboratories for various purposes such as preparing saline solutions, conducting chemical reactions, and as a drying agent. It also has numerous industrial applications, including in the manufacture of chemicals, pharmaceuticals, and in food processing.
Lab-grade sodium chloride is often stored in tightly sealed containers to prevent contamination and to maintain its purity. To maintain the quality and integrity of the product, it is recommended to store Sodium Chloride in a cool, dry place, away from moisture and extreme temperature fluctuations. The original packaging, if tightly sealed, can help prevent contamination and moisture absorption. Merck KGaA's Sodium Chloride in a 1-kilogram package is a reliable and high-purity source of this essential chemical reagent for laboratory and industrial applications, offering the quality assurance and precision that is characteristic of products from this reputable manufacturer.
