Product Code : SCL-LC-12281
Potassium Nitrate (SKU SCL-LC-12281), KNO3, is the potassium salt of nitric acid and an oxidising inorganic nitrate. It suits supervised school and college practicals on solubility, crystallisation, nitrate ions and qualitative salt analysis, and lessons on how oxidisers are stored. Science Lab Supplies sends it out from Ambala, India, on quotation to schools, colleges, science departments, tender contractors and distributors, for laboratory use only.

Applications and Experiments for Potassium Nitrate
The salt can be used to measure solubility at different temperatures and to demonstrate recrystallisation, with the water warmed by a Bunsen Burner (Pack of Two) under a Cast Iron Tripod Stand. It also supports nitrate-ion tests and oxidiser-classification lessons; dispense it with a dry spatula and keep it from fuels.
- Class 9 science (Is matter around us pure?): solubility of a salt at different temperatures.
- Class 11–12 chemistry: plotting a solubility curve and recrystallising a salt.
- Class 11–12 salt analysis: tests for the nitrate anion and the potassium cation.
- Safety lessons: segregating oxidisers from combustible and organic materials.
Standard Scope of Supply
You receive one pack of Potassium Nitrate with a batch label, the Safety Data Sheet, shelf-life detail 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. Grade and pack size are confirmed in writing on the quotation.
Packing, MOQ and Lead Time
Order a single pack for one chemistry room or a larger quantity for several institutions; the quotation shows the packing, delivery time and price for exactly that amount. Other nitrate or chloride salts can be added, and school chemistry lab equipment in India for the same practical can be quoted together.
Using its Importer-Exporter Code as a registered exporter, Science Lab Supplies can ship to buyers in Uganda, the UAE, Saudi Arabia, Oman, the Philippines and Nepal. A solubility-practical order can be explained on the contact page or assembled item by item in the enquiry cart, while government purchasers can begin at the lab tender page.
Frequently Asked Questions
What is Potassium Nitrate used for in a laboratory?
It is an inorganic nitrate salt for supervised solubility and crystallisation work, qualitative analysis of nitrate and potassium ions, and lessons on how oxidisers are classified and stored.
Is this nitrate salt hazardous?
Yes, it is an oxidiser. Keep it tightly closed in a cool, dry store away from combustibles, reducing agents and organic materials, and do not heat it unnecessarily or mix it with fuels.
Who supplies the Potassium Nitrate?
This salt is packed and invoiced by Science Lab Supplies in Ambala, India, with a labelled batch and Safety Data Sheet, and it can be priced alone or beside other salts.
Can it be used for pyrotechnics?
No. This potassium nitrate is for laboratory and teaching use only and is not supplied for pyrotechnic, explosive, fuel-mixture or consumer purposes. In class it is handled only in supervised practicals.
