Sodium Peroxide is a yellowish-white inorganic compound known for its strong oxidizing properties and use in various chemical and industrial processes.
🏭⚗️ Production
Sodium peroxide is produced by the direct reaction of sodium metal with oxygen gas. Typically, sodium is burned in an excess of oxygen at elevated temperatures, which leads to the formation of sodium peroxide. The resulting solid is collected, purified, and stored in airtight containers to prevent decomposition.
🔬 Properties
Sodium peroxide appears as a yellowish-white crystalline solid that is highly reactive and strongly oxidizing. It readily reacts with water to produce sodium hydroxide and oxygen gas. It has a melting point of approximately 460 °C and is soluble in water with vigorous evolution of oxygen. The compound decomposes upon exposure to moisture or heat, releasing oxygen.
🧪 Applications
Sodium peroxide is used as a bleaching agent, disinfectant, and oxidizer in chemical syntheses. It finds applications in the paper and textile industries for bleaching, and in environmental chemistry for oxygen generation. It can also be used in the purification of metals and as a reagent in organic and inorganic reactions requiring a strong oxidizing agent.
⚠️ Safety
Due to its strong oxidizing nature, sodium peroxide must be handled with extreme caution. It can cause severe burns upon contact with skin or eyes and can ignite combustible materials. It reacts violently with water and acids, releasing oxygen gas that may cause fire or explosion hazards in confined spaces. Proper personal protective equipment, including gloves, eye protection, and lab coats, should be used. Storage in a cool, dry place away from moisture and incompatible substances is essential, and disposal must follow strict regulatory guidelines.
