Product Code : SCL-LC-12281
Potassium Nitrate (SKU SCL-LC-12281), KNO3, is the potassium salt of nitric acid and an oxidising inorganic nitrate. Schools and colleges use it in supervised practicals on solubility, crystallisation, nitrate ions and qualitative salt analysis, and to teach how oxidisers are stored. Science Lab Supplies delivers it from Ambala, India, to schools, colleges, science departments, tender contractors and distributors; this listing covers laboratory use only.
Specifications
The salt is KNO3, an oxidising nitrate that must be stored apart from combustibles, reducing agents and organic materials. It is supplied for teaching and laboratory work, not for any consumer or pyrotechnic purpose. Grade, assay, physical form and pack size are set out on the quotation and batch label.

Applications and Experiments for Potassium Nitrate
Teachers commonly use the salt to measure solubility at different temperatures and to demonstrate recrystallisation. It also supports nitrate-ion tests and lessons on oxidiser classification. Staff should dispense it with a clean, dry spatula, keep it away from fuels and reducing agents, and avoid unnecessary heating.
- 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.
- Laboratory 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 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. Reach the team through the contact page, shortlist items in the enquiry cart, or open the lab tender page for bid support.
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?
Science Lab Supplies is the supplier, dispatching from Ambala, India, with the Safety Data Sheet and a labelled batch. It can be quoted on its own or with other salts.
Can students use it in practicals?
Yes, in supervised school and college practicals where trained staff control dispensing, heating and disposal. It should not be issued for unsupervised handling.
