sodium sulfite price

Sodium sulfite (chemical formula: Na₂SO₃) is an inorganic compound commonly found in anhydrous and heptahydrate forms (Na₂SO₃·7H₂O). Below are its main characteristics:

Physical Properties:

Anhydrous Form: White powder, highly soluble in water, slightly soluble in ethanol.

Heptahydrate: Colorless crystals, highly soluble in water, prone to efflorescence in air.

Chemical Properties:

Reducing Agent: Sodium sulfite is a strong reducing agent, reacting with oxidizers to form sodium sulfate.

Reaction with Acids: Reacts with acids to release sulfur dioxide gas.

Stability: Stable in dry air but easily oxidized to sodium sulfate in humid environments.

Safety Precautions:

Inhalation: May irritate the respiratory tract; use in well-ventilated areas.

Contact: May irritate skin and eyes; wear protective equipment during handling.

Ingestion: Harmful if swallowed; avoid accidental ingestion.

Storage Methods:

Dry Conditions: Store in a dry, cool place, avoiding moisture.

Sealed Containers: Keep containers tightly sealed to prevent oxidation and moisture absorption.

Food Industry:

Preservative: Used to prevent oxidation and browning, extending shelf life.

Bleaching Agent: Used to bleach foods such as dried fruits and sugars.

Water Treatment:

Dechlorination Agent: Used to remove residual chlorine from water, protecting downstream equipment.

Antioxidant: Prevents dissolved oxygen in boiler water from corroding metals.

Chemical Industry:

Reducing Agent: Used in organic synthesis and dye production.

Neutralizing Agent: Used to adjust solution pH.

Photography Industry:

Developing Agent: Used in photo development to prevent oxidation of the developer.

Textile Industry:

Bleaching Agent: Used to bleach textiles.

Reducing Agent: Assists in dye fixation during the dyeing process.

Pharmaceutical Industry:

Antioxidant: Used in drug formulations to prevent oxidative degradation.

Environmental Protection:

Waste Gas Treatment: Used to absorb sulfur dioxide from industrial exhaust, reducing pollution.
