Sodium Thiosulfate 100 g
Sodium Thiosulfate 100 g (Product Code: SCI-753/330) is an analytical reagent salt used for rate-of-reaction and iodometric titration practicals in school and college chemistry laboratories. The 100 g pack suits a department running the “disappearing cross” experiment or preparing standard thiosulfate solution, and an MSDS is supplied with it. Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, supplies it together with the glassware for a complete titration kit for schools.

What Is Sodium Thiosulfate Used For?
In the best-known school practical, sodium thiosulfate solution reacts with dilute hydrochloric acid to form a pale yellow sulfur precipitate. Students time how long it takes for a cross drawn under the flask to disappear, then repeat at different concentrations or temperatures to plot how reaction rate changes. The same reaction gives a simple, reproducible demonstration of collision theory.
In volumetric analysis, sodium thiosulfate solution is titrated against iodine: it reduces iodine to colourless iodide, and a few drops of starch near the end point sharpen the colour change. This is the basis of iodometric determinations of oxidising agents at senior-school and undergraduate level. Weigh the crystals on a clean balance, dissolve in freshly boiled and cooled distilled water, and keep solutions in closed bottles.
Supplier
Sodium Thiosulfate 100 g is sourced and supplied by Jain Scientific Equipments Private Limited, which trades as ScienceLab from Ambala, Haryana, India. Because the company also lists burettes, flasks, stopwatches and indicators, a chemistry teacher can request everything for a rate or titration practical in a single enquiry. The ScienceLab profile has company details.

Frequently Asked Questions
What is Sodium Thiosulfate 100 g used for in schools?
Sodium Thiosulfate 100 g is mainly used for the disappearing-cross rate-of-reaction practical with dilute hydrochloric acid and for iodometric titrations with iodine and starch indicator. Both are standard experiments in secondary and college chemistry courses.
What grade and quantity is this sodium thiosulfate?
Sodium Thiosulfate 100 g, code SCI-753/330, is an analytical reagent grade chemical in a 100 g pack. For standard solutions, ask us for the batch details with your quotation if your method needs the exact assay.
Does Sodium Thiosulfate 100 g come with safety information?
Yes, Sodium Thiosulfate 100 g is supplied with an MSDS. Keep it in the chemical register and follow its guidance on storage, handling and disposal, especially when the salt is used alongside hydrochloric acid, which releases sulfur dioxide.
What is the shelf life of Sodium Thiosulfate 100 g?
Shelf life depends on the chemical, its grade and storage conditions; ask us for the expiry date of the batch you are quoted. Keep Sodium Thiosulfate 100 g sealed in a cool, dry place, and prepare titration solutions fresh.
Who supplies Sodium Thiosulfate 100 g?
