Sodium Thio Sulphate

Product Code : SCL-LC-12275

The Sodium Thio Sulphate lab chemical is an inorganic thiosulfate reagent used for supervised chemistry experiments, iodometric titration, solution preparation, dechlorination demonstrations, and reducing-agent teaching. It is suitable for schools, colleges, chemistry laboratories, science departments, institutional tenders, distributors, and educational procurement buyers.

Product Description

Sodium Thio Sulphate from Science Lab Supplies is intended for controlled educational and laboratory use where a sodium thiosulphate reagent is required. The exact hydrate form, grade, assay, pack size, physical form, batch number, shelf life, SDS, COA, and regulatory documents must be confirmed before final publication or quotation.

Sodium thiosulphate is commonly represented as Na₂S₂O₃ in anhydrous form and as Na₂S₂O₃·5H₂O when supplied as pentahydrate. In teaching laboratories, it supports iodine-thiosulphate titration, redox chemistry, reaction-rate demonstrations, and standard solution work where the syllabus, SOP, and SDS permit.

Key Features

• Thiosulfate reagent: suitable for supervised chemistry teaching and approved laboratory reagent preparation.
• Iodometric titration support: commonly used in iodine-based redox titration practicals when correctly standardized.
• Hydrate verification required: formula weight changes between anhydrous and pentahydrate forms.
• Reducing-agent chemistry: supports lessons on redox reactions, iodine reduction, and thiosulfate ion behaviour.
• Solution preparation use: suitable for preparing approved laboratory solutions under institutional procedures.
• Pack size verification: supplied quantity and container type must be confirmed from the final quotation.
• Documentation-led procurement: SDS, COA, assay, batch number, and shelf-life details should be verified before use.

• Supporting tender-based procurement for chemistry lab chemical inventories

How to Use the Sodium Thio Sulphate

1. Read the current SDS, product label, and institutional risk assessment before use.
2. Confirm the hydrate form before weighing, because anhydrous and pentahydrate forms have different formula weights.
3. Wear suitable PPE, including lab coat, gloves, and eye protection.
4. Use only the quantity required by the approved laboratory procedure.
5. Measure the chemical with a clean, dry spatula or weighing tool.
6. Prepare solutions only in approved glassware or containers using the stated method.
7. Label prepared solutions with chemical name, concentration, date, and safety notes.
8. Dispose of residues according to institutional chemical-waste rules.

Safety note: Use Sodium Thio Sulphate only in supervised laboratory procedures. Do not ingest, inhale dust, mix with acids outside an approved experiment, heat unnecessarily, or combine with unknown chemicals without SDS review.

Care & Maintenance

• Store tightly closed in a cool, dry, ventilated chemical-storage area.
• Keep away from acids, strong oxidizers, moisture-sensitive documentation, food items, and unlabelled containers.
• Use clean, dry tools and avoid returning unused material to the original pack.
• Maintain SDS, COA, batch number, hydrate form, pack size, and shelf-life records for audit control.

Frequently Asked Questions

What is Sodium Thio Sulphate used for in a laboratory?

Sodium Thio Sulphate is used as a thiosulfate reagent for supervised chemistry teaching, iodometric titration, redox demonstrations, solution preparation, and approved dechlorination activities.

What is the formula of Sodium Thio Sulphate?

The anhydrous formula is Na₂S₂O₃. If supplied as pentahydrate, it is written as Na₂S₂O₃·5H₂O.

Is Sodium Thio Sulphate the same as Sodium Thiosulfate?

Yes. “Sodium Thio Sulphate,” “sodium thiosulphate,” and “sodium thiosulfate” are commonly used spelling variants, but the product label should confirm the exact chemical and hydrate form.

What grade is supplied?

The grade is not confirmed. Add LR, AR, ACS, analytical, technical, assay, or purity details only after verifying the product label, COA, or datasheet.

Is it suitable for school chemistry labs?

Yes. It is suitable for supervised school and college chemistry laboratories when handled by trained users under approved practical procedures and SDS-based safety controls.

Does it include SDS or COA?

SDS and COA availability must be confirmed for the final supply. These documents should be requested before procurement, storage, transport, classroom use, or disposal planning.
