Sodium sulfite, with the chemical formula Na2SO3, has the CAS number 7757-83-7. It appears as a white crystalline powder with no odor. Sodium sulfite is composed of two sodium ions (Na+) and one sulfite ion (SO3^2-). This compound is highly soluble in water. It is important to handle sodium sulfite with caution as it can cause irritation to the skin, eyes, and respiratory system. Ingestion or inhalation of sodium sulfite may cause nausea, vomiting, and difficulty breathing. It is also important to avoid exposure to high temperatures, as sodium sulfite may decompose and release toxic fumes. Sodium sulfite is primarily used as a reducing agent and preservative in various industries. It is commonly used in the food and beverage industry to prevent oxidation and maintain the color and flavor of products. Sodium sulfite is also used in water treatment processes to remove excess chlorine and as a bleaching agent in the textile industry.
Applicable Fields
