FAQ's of Sodium Metabishulphite:

Q: How should Sodium Metabisulphite be stored for optimal stability?

A: Sodium Metabisulphite should be stored in a cool, dry, and well-ventilated area with the container tightly closed. HDPE bags or drums are ideal for packaging, preventing moisture and contamination, which helps extend its shelf life to up to 24 months.

Q: What are the main uses of Sodium Metabisulphite in laboratories and industries?

A: Sodium Metabisulphite is used predominantly as a preservative, antioxidant, and water treatment chemical. It finds applications in laboratory research, pharmaceuticals, the food industry, and water treatment processes due to its effective sulphite content and extra pure grade.

Q: What benefits does Sodium Metabisulphite offer in food processing?

A: In food processing, Sodium Metabisulphite serves as a preservative and antioxidant that maintains product freshness, prevents microbial growth, and guards against oxidative spoilage, making it a valuable additive for extending shelf life and ensuring safety.

Q: When should safety precautions be observed with Sodium Metabisulphite?

A: Safety precautions should be taken at all times during handling, particularly because Sodium Metabisulphite is classified as Class 8 - Corrosive. Use personal protective equipment and avoid inhalation of dust. Store in sealed containers away from incompatible substances.

Q: What is the typical pH level of a Sodium Metabisulphite solution and why does it matter?

A: A 1% solution of Sodium Metabisulphite in water exhibits a pH of 4.0-5.5. This mildly acidic nature is important for its efficacy as a preservative and its compatibility with various chemical processes.

Q: Where is Sodium Metabisulphite commonly distributed and supplied in India?

A: Sodium Metabisulphite is provided by distributors, importers, manufacturers, suppliers, and traders across India. It is available in different packaging sizes to meet the requirements of academic, industrial, and commercial clients.
