Key Properties
Sodium (metal) lumps 99% AR is a high-purity analytical reagent characterized by its extreme reactivity and is primarily used in laboratory settings for precise analytical and synthetic applications. This AR-grade sodium is produced with stringent purity controls, ensuring a minimum purity of 99%, making it suitable for sensitive chemical reactions and analyses. Sodium is a soft, silvery-white alkali metal that is highly reactive, particularly with water, and must be handled with care. The product is supplied in lump form and is coated with liquid paraffin to prevent oxidation and moisture exposure, which could lead to hazardous reactions.
Also known as Sodium metal.

- Substance
Sodium metal appears as soft, silvery-white lumps and is typically stored submerged in oil to prevent contact with moisture and air. The melting point of sodium is approximately 97.79 °C, while its boiling point is around 883 °C. Sodium has a density of about 0.97 g/cm³ at 20 °C and is highly soluble in water, reacting vigorously to produce sodium hydroxide and hydrogen gas. The vapour pressure of sodium is negligible at room temperature, and it has a low viscosity, making it easy to handle in its solid state. The product is classified as flammable and should be stored away from heat sources.
