Sodium Sulphite – 500 gram Pack

Sodium sulphite is a inorganic sulfur(IV) salt used in laboratory chemistry. Readily oxidizes to sulfate and acts as a reducing reagent. It is supplied here under the product listing “Sodium Sulphite – 500 gram Pack” in a 500 g pack for institutional laboratory procurement. Its chemical behaviour makes it relevant to redox reaction studies and oxygen-scavenging experiments, depending on the specific method, reagent concentration and other materials present. The product should be selected by confirming its exact chemical form, relevant composition and compatibility with the intended protocol. Where the listing does not identify a hydrate, formula mass and registry designation must be confirmed against the actual manufacturer label rather than assumed from a related form. This material is intended for properly equipped educational, analytical and research settings under established laboratory procedures. Appropriate storage, protective equipment and chemical waste management are essential, particularly where hazardous reactions or releases are possible.

Frequently Asked Questions About Sodium sulphite

What is Sodium sulphite used for in a laboratory?

One scientifically relevant role is redox reaction studies and oxygen-scavenging experiments. The material is not automatically suitable for every experiment, and users should follow a validated procedure with appropriate concentration, controls and protective measures.

What is the formula and molecular weight of Sodium sulphite?

The listing identifies Sodium sulphite. Formula: Na2SO3 (anhydrous form); molecular weight or formula mass: 126.04 (anhydrous). If a hydrate or mixture is not identified precisely, its exact formula mass must be confirmed from the supplied product identity.

What CAS number identifies Sodium sulphite?

The registry information for this listing is 7757-83-7 (anhydrous). For substances offered in several hydrate states or formulations, confirm the exact CAS identity on the manufacturer label before catalog publication or purchase.

Is Sodium sulphite suitable for educational laboratory work?

It may be relevant to carefully selected supervised investigations such as redox reaction studies and oxygen-scavenging experiments. Its suitability depends on the hazards, age and training of users, local laboratory controls, and the exact chemical composition.

How should Sodium sulphite be handled and stored?

Store closed, dry and separated from acids and oxidizers. Can release sulfur dioxide upon acidification; avoid breathing dust or gas. Review the current manufacturer Safety Data Sheet and follow institutional spill, exposure and waste procedures. Never substitute generic safety assumptions for the actual formulation.

Storage Conditions for Sodium sulphite

Store closed, dry and separated from acids and oxidizers. Store in original or chemically compatible properly labelled containers and segregate from incompatible reagents. Prevent accidental contamination, unauthorized handling and environmental release. Refer to the current manufacturer Safety Data Sheet for any specialized storage limits relevant to this formulation or hydrate.

Precautions for Handling Sodium sulphite

Consult the current Safety Data Sheet before opening or using the reagent. Can release sulfur dioxide upon acidification; avoid breathing dust or gas. Wear a suitable lab coat, chemical-resistant gloves and eye protection; use local extraction or a fume hood when dust, vapour or hazardous gas may be produced. Do not mix with incompatible reagents. Ensure trained supervision for hazardous procedures, and follow local spill, emergency-response and chemical-waste protocols.
