Sodium Acetate CAS#127-09-3
Sodium acetate (CH₃COONa) is the sodium salt of acetic acid and appears as a colorless, deliquescent crystalline substance. It is a versatile chemical with a wide range of industrial, laboratory, and commercial applications.
In the textile industry, sodium acetate is used to neutralize sulfuric acid-containing waste streams and can serve as a photoresist when aniline dyes are employed. In the construction sector, it is utilized as a concrete sealant to help reduce water-related damage. In the food industry, it is commonly used as a seasoning agent.
Sodium acetate is also widely used as a buffering agent in laboratory applications. In addition, it is an important component in heating pads, hand warmers, and hot ice systems due to its heat-storage properties.
For laboratory preparation, sodium acetate can be produced through the reaction of acetic acid with sodium carbonate, sodium bicarbonate, or sodium hydroxide. Industrially, it is typically manufactured by reacting glacial acetic acid with sodium hydroxide.
