Sodium Nitrate
Sodium Nitrate (Product Code: SCI-653/285) is an analytical reagent grade Group 1 nitrate used to show how alkali-metal nitrates decompose on heating and to give the strong yellow sodium flame in school and college chemistry laboratories. Also known as Chile saltpetre, it comes in a 200 g pack with an MSDS for teaching labs, agricultural science practicals and research benches. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, a lab chemicals supplier in India.

What Is Sodium Nitrate Used For?
When sodium nitrate is heated strongly in a hard-glass or boiling tube, it melts and gives off oxygen, which relights a glowing splint, leaving sodium nitrite behind. No brown nitrogen dioxide appears, unlike the nitrates of lead or copper, so heating the two types side by side is a memorable way to show how thermal stability changes across the reactivity series in a school chemistry lab.
A trace of the salt on a clean wire loop gives the intense, lasting yellow flame typical of sodium, a useful reference colour in flame test practicals. In agriculture and biology labs, sodium nitrate also serves as a soluble nitrogen source in plant nutrition experiments. It is an oxidiser that attracts moisture, so keep the lid tight, store it away from combustibles and clean up spills promptly.
Supplier
Under the ScienceLab name, Jain Scientific Equipments Private Limited supplies Sodium Nitrate to schools, colleges, agricultural institutes and trade buyers, together with the MSDS for their chemical records. Laboratories building a nitrate comparison set can request this salt with other nitrates from the same catalogue in one quotation. Visit the ScienceLab profile for details about the company.

Chemicals and apparatus for nitrate decomposition and flame test comparisons:
- Sodium Nitrite — the product left after heating, useful for comparison.
- Lead Nitrate — a nitrate that gives brown fumes, for contrast.
- Boiling Tube — for heating the salt strongly.
- Bunsen Burner — provides the heat and the flame for flame tests.
- Potassium Nitrate 200 g — another Group 1 nitrate for side-by-side work.

Frequently Asked Questions
What happens when Sodium Nitrate is heated?
When Sodium Nitrate is heated strongly it melts and decomposes into sodium nitrite and oxygen, which relights a glowing splint. Unlike copper or lead nitrate, it gives off no brown nitrogen dioxide, a key point when comparing the thermal stability of nitrates.
What is Sodium Nitrate used for in school labs?
Sodium Nitrate is used in school labs for thermal decomposition comparisons, as a yellow flame test sample, as a nitrate source for ion tests and in plant nutrition experiments. This listing is a 200 g analytical reagent pack supplied with an MSDS.
Is Sodium Nitrate the same as sodium nitrite?
No. Sodium Nitrate contains the nitrate ion and turns into sodium nitrite only when heated strongly, while sodium nitrite is a separate, more toxic chemical with different uses. Check the name and code SCI-653/285 carefully when you order.
What precautions apply to Sodium Nitrate?
Sodium Nitrate is an oxidiser that can make a fire burn more fiercely, and it is harmful if swallowed in quantity. Wear eye protection, keep it away from fuels and reducing agents, and store it in a closed container because it absorbs moisture.
Does Sodium Nitrate have an expiry date?
Shelf life depends on the chemical, its grade and storage conditions; ask us for the expiry date of the batch you are quoted. Sodium Nitrate that is kept sealed and dry stays free-flowing for longer than a pack left open to humid air.
Who supplies Sodium Nitrate SCI-653/285?
Sodium Nitrate SCI-653/285 is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, in 200 g analytical reagent packs with MSDS, to institutions and dealers in India and international markets.
