natriumasetta

Natriumasetta is the Swedish name for sodium acetate. Sodium acetate is the sodium salt of acetic acid. It is a chemical compound with the formula CH3COONa. In its anhydrous form, it is a white crystalline solid. It is soluble in water. Sodium acetate can be produced by the reaction of sodium hydroxide or sodium carbonate with acetic acid. It is commonly used as a food additive, often designated by the E number E262. In food, it is used as a preservative and a seasoning. It can impart a salty and vinegary flavor. Beyond its culinary applications, sodium acetate has various industrial uses. It is employed in textile dyeing, as a mordant, to help fix dyes to fabrics. It is also utilized in concrete construction to prevent efflorescence, which is the formation of a white powdery layer on the surface. In medicine, it can be found in some intravenous fluids. Another interesting application is in reusable heat packs. When sodium acetate trihydrate is heated and then cooled, it can be induced to crystallize, releasing heat. This process can be reversed by reheating the pack.
