제품 설명
High Quality CAS7757-83-7 Sodium Sulfite Powder Na2SO3 97% For Printing
Product Introduction
Sodium sulfite is a white, water-soluble powder with the chemical formula Na₂SO₃. This compound consists of sodium, sulfur, and oxygen atoms.
Its primary function is as an oxygen scavenger. It readily reacts with atmospheric oxygen, making it valuable as an antioxidant preservative in food and beverages to maintain freshness and prevent discoloration. This same property makes it effective for water treatment to remove chlorine.
Additionally, sodium sulfite serves important roles in paper manufacturing and photographic processing. This versatile chemical protects products from oxidative damage and chemical degradation, extending the shelf life of various consumer goods.
