Sodium Thio Sulphate Hypo – 500 gram Packs

Sodium thiosulphate is a inorganic thiosulfate salt used in laboratory chemistry. Moderate reducing agent that reacts stoichiometrically with iodine. It is supplied here under the product listing “Sodium Thio Sulphate Hypo – 500 gram Packs” in a 500 g pack for institutional laboratory procurement. Its chemical behaviour makes it relevant to iodometric titration and residual chlorine analysis under validated conditions, 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 thiosulphate

What is Sodium thiosulphate used for in a laboratory?

One scientifically relevant role is iodometric titration and residual chlorine analysis under validated conditions. 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 thiosulphate?

The listing identifies Sodium thiosulphate. Formula: Hydrate-dependent: Na2S2O3·xH2O; molecular weight or formula mass: Hydrate-dependent. 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 thiosulphate?

The registry information for this listing is Hydrate-dependent. 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 thiosulphate suitable for educational laboratory work?

It may be relevant to carefully selected supervised investigations such as iodometric titration and residual chlorine analysis under validated conditions. Its suitability depends on the hazards, age and training of users, local laboratory controls, and the exact chemical composition.

How should Sodium thiosulphate be handled and stored?

Store closed, cool and dry, away from strong acids and oxidizers. Acids can cause sulfur dioxide liberation and sulfur precipitation. 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 thiosulphate

Store closed, cool and dry, away from strong 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 thiosulphate

Consult the current Safety Data Sheet before opening or using the reagent. Acids can cause sulfur dioxide liberation and sulfur precipitation. 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.
