Frequently Asked Questions:

What is the primary function of Sodium Sulphite in food preservation?

In the food industry, it serves primarily as an antioxidant to prevent browning and discoloration in fruits, vegetables, and seafood. It also acts as a preservative by inhibiting the growth of microorganisms, thereby extending the shelf life of products like dried fruits, wine, and fruit juices.

In water treatment, it is used as an oxygen scavenger. It chemically reacts with dissolved oxygen in boiler feedwater to form sodium sulfate, thereby removing the oxygen that would otherwise cause severe corrosion and pitting of metal pipes and tanks.

How does Sodium Sulphite prevent corrosion in boiler systems?

Sodium Sulphite can be irritating to the skin, eyes, and respiratory system. Dust may form in handling. Personal protective equipment (PPE) including gloves, safety goggles, and a dust mask is essential. It should be handled in a well-ventilated area. Avoid contact with strong acids, as this can release toxic sulfur dioxide gas. Always refer to the Safety Data Sheet (SDS) for comprehensive handling and hazard information.

What safety precautions are necessary when handling this chemical?

It should be stored in a cool, dry, well-ventilated place in a tightly sealed container. It is important to keep it away from moisture and incompatible materials, particularly strong acids and oxidizing agents, to prevent decomposition or hazardous reactions.

How should Sodium Sulphite be stored?

Yes. A comprehensive Safety Data Sheet (SDS) and detailed technical data sheet are available upon request and must be reviewed thoroughly before handling or using this product to ensure safe and effective application.
