Product Description




Sodium Metabisulfite Product Description


 

Welcome to Guangzhou Zhifan Chemical Co., Ltd.

 

Product Description: Sodium Metabisulfite

 

Sodium metabisulfite (Na2S2O5) is a versatile inorganic compound available in white or yellow crystals with a distinctive pungent odor. It is highly soluble in water, resulting in an acidic aqueous solution. When exposed to strong acids, it liberates sulfur dioxide and forms corresponding salts. However, prolonged exposure to air leads to oxidation into sodium sulfate, necessitating short-term storage.

 

Our company, Guangzhou Zhifan Chemical Co., Ltd., offers high-quality sodium metabisulfite that meets industry standards for various applications.
