Sodium Meta Bi Sulphite Extra Pure – 500 gram Packs

Sodium Meta Bi Sulphite Extra Pure is a laboratory catalog product associated with reducing sulfur(IV) salt and scientific work involving bisulfite equilibria and reduction chemistry. It produces bisulfite species in water and can release sulfur dioxide on acidification. The exact chemical identification is important for interpreting stoichiometry, test outcomes, solubility and reagent compatibility. Teaching laboratories and analytical research groups may use appropriately selected materials for established investigations, but the actual experimental purpose must match the supplied composition and grade. In particular, controlled work with this product can illustrate characteristic inorganic or solution chemistry while strengthening an understanding of reaction mechanisms and analytical observations. It should not be treated as universally suitable for classroom or quantitative procedures. Personnel must consider the substance-specific hazards, proper protective equipment, incompatible reagents and regulated disposal before using this material. Where the product name does not establish hydration, composition or a unique identity, confirm these details from its original supplier documentation before use.

Frequently Asked Questions About Sodium Meta Bi Sulphite Extra Pure

What are the main laboratory uses of Sodium Meta Bi Sulphite Extra Pure?

This material is associated with bisulfite equilibria and reduction chemistry. Typical contexts include sulfite-redox investigations and bisulfite reagent solution preparation. Each use requires an appropriate method, confirmed identity and suitable handling controls; restricted or highly reactive substances should not be used in unsupervised student exercises.

What formula and molecular weight apply to Sodium Meta Bi Sulphite Extra Pure?

The applicable formula entry is Na2S2O5, with a formula-mass entry of 190.11. Some product names cover hydrated, commercial or mixed forms, so a theoretical formula does not necessarily describe the supplied material. Check the container label and relevant supplier documents before using these figures in calculations.

What CAS number identifies Sodium Meta Bi Sulphite Extra Pure?

The identifier information for this listing is 7681-57-4. This refers to the stated chemical basis where indicated; the actual product may require a different hydrate or composition identifier. Never substitute the CAS of a related compound solely because its trade name appears similar.

Is Sodium Meta Bi Sulphite Extra Pure suitable for college and research laboratories?

This reagent may support selected supervised analytical or research procedures where its form, grade and risks have been evaluated. It is not automatically appropriate for every method or for ordinary school practicals. The institution should establish controls based on the current safety data and procedure.

How should Sodium Meta Bi Sulphite Extra Pure be stored and handled?

Use a clearly labelled compatible container and follow the supplied Safety Data Sheet for exposure controls, incompatibilities, ventilation and spill response. Some salts are oxidizers, corrosive or moisture sensitive, and sodium metal requires specialist water-reactive handling. Collect residues through the institutional hazardous-waste procedure.

Storage Conditions for Sodium Meta Bi Sulphite Extra Pure

Keep closed and dry, separated from acids and oxidizers and protected against moisture contamination. Confirm any additional moisture, light and chemical segregation requirements from the product-specific documentation before storing a new lot.

Precautions for Handling Sodium Meta Bi Sulphite Extra Pure

Acid contact can release sulfur dioxide. Avoid dust and vapours, provide appropriate ventilation and wear gloves and eye protection; do not mix with incompatible oxidants. Review the current Safety Data Sheet, use suitable protective gloves and eye protection, and apply approved spill response and waste segregation procedures. Restrict handling to trained laboratory personnel and avoid environmental release.
