Product Code : SCL-LC-12285
Potassium Iodide (SKU SCL-LC-12285), KI, is an inorganic iodide salt used to prepare iodine solutions, run starch-iodine tests, show iodide precipitation reactions and support iodometric titration. It is a routine reagent in school biology and chemistry rooms as well as college analytical labs. Science Lab Supplies offers it from Ambala, India, to schools, colleges, training institutes, tender contractors and distributors, for laboratory use only and not as a medicine or supplement.
Specifications
The reagent is potassium iodide, KI, an iodide salt that is dissolved to give solutions for iodine chemistry and redox work. Prepared solutions should be protected from unnecessary light where the method asks. Grade, assay, physical form and pack size are confirmed on the quotation and batch label.

Applications and Experiments for Potassium Iodide
Most schools use the salt to dissolve iodine for the iodine solution that tests leaves and foods for starch, and to show the precipitate formed when iodide meets lead ions. College labs use it in iodometric titrations. Wear gloves and eye protection, weigh with a clean, dry spatula and label all solutions.
- Class 10 science (photosynthesis): iodine solution prepared with potassium iodide for the leaf starch test.
- NCERT Class 10 science, Chapter 1: double-displacement reaction of potassium iodide with lead nitrate, shown by the teacher.
- B.Sc. volumetric analysis: iodometric titrations with sodium thiosulphate.
- Class 11–12 chemistry: halide and iodide-ion reactions in qualitative analysis.
Standard Scope of Supply
One pack of Potassium Iodide is supplied per order line, with a batch label, the Safety Data Sheet and transport documents. Shelf life depends on the chemical, its grade and storage conditions; ask us for the expiry date of the batch you are quoted. The quotation confirms grade and pack size.
Packing, MOQ and Lead Time
You can ask Science Lab Supplies to quote one pack or stock for many schools; each quotation states packing, delivery time and price for that quantity. Iodine crystals and thiosulphate for the same practicals can go on one request to this laboratory chemicals supplier in India.
Science Lab Supplies, a registered exporter with an Importer-Exporter Code, can ship to buyers in the Philippines, Nepal, Bangladesh, Zambia, Rwanda and South Africa. Send enquiries via the contact page, gather products in the enquiry cart, or look at the lab tender page for public procurement.
Frequently Asked Questions
Why is potassium iodide used to make iodine solution?
Iodine on its own dissolves poorly in water, so the teacher dissolves it in potassium iodide solution to make the iodine reagent used in starch testing and iodine chemistry.
Is Potassium Iodide suitable for school labs?
Yes. It suits supervised school and college practicals handled under the teacher's procedure. Avoid ingestion, dust and mixing with unknown chemicals, and follow the Safety Data Sheet.
Who supplies the Potassium Iodide?
Science Lab Supplies supplies this salt from Ambala, India, with its Safety Data Sheet and batch label, and it can be combined with other reagents on one quotation.
Can it be used as medicine?
No. This listing is for laboratory-use potassium iodide only. It must not be used as a medicine, supplement, radiation-protection tablet, food ingredient or consumer product.
