Key Properties
Sodium hydroxide (NaOH), commonly known as caustic soda, is a highly versatile and widely used inorganic compound. This AR-grade sodium hydroxide is produced with stringent purity controls, making it suitable for precise analytical applications. It is a strong base that readily dissociates in water, producing hydroxide ions, which makes it essential in various chemical reactions and processes. The pellets are designed for easy handling and storage, ensuring minimal exposure to moisture and degradation.
Also known as Caustic soda, Lye.

- Substance
Sodium hydroxide appears as white, solid pellets that are highly hygroscopic, meaning they readily absorb moisture from the air. The melting point of sodium hydroxide is approximately 318 °C, while its boiling point is around 1380 °C. It has a density of about 2.13 g/cm³ at 20 °C. Sodium hydroxide is highly soluble in water, with a solubility of approximately 1110 g/L at 20 °C, and it generates a significant amount of heat upon dissolution. The compound has a pH value of around 13 when dissolved in water, indicating its strong basicity.
