Red Phosphorus 50 g Manufacturer,Supplier and Exporter in India

Red Phosphorus 50 g (Product Code: SCI-519/224) is an analytical reagent grade allotrope of phosphorus used to demonstrate allotropy and the combustion of a non-metal in college and senior school chemistry laboratories. The compact 50 g pack, supplied with an MSDS, suits demonstration work where only a spatula tip is burned at a time. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India.

What Is Red Phosphorus Used For?

Teachers use red phosphorus to show that one element can exist in forms with very different properties. Unlike white phosphorus, the red form is stable in air, does not glow in the dark and does not have to be kept under water, so it is the practical choice for school chemistry lab equipment in India. Heated on a deflagrating spoon and lowered into a gas jar of oxygen, a small portion burns with a bright flame and dense white smoke of phosphorus(V) oxide.

Shaking that smoke with a little water gives an acidic solution that turns blue litmus red, a neat demonstration that non-metal oxides are acidic. Red phosphorus is also the active part of the striking strip on safety-match boxes, a useful talking point in everyday-chemistry lessons. It is a flammable solid: keep it dry and away from flames, and never mix or grind it with oxidisers such as potassium chlorate, because such mixtures can explode on friction.

Supplier

Red Phosphorus 50 g is supplied by Jain Scientific Equipments Private Limited, which trades as ScienceLab and serves laboratories from Ambala, Haryana. Because it is a flammable solid, tell us the destination when you enquire so that shipping options can be confirmed with the quotation. Company information is on the ScienceLab profile page.

Related Laboratory Equipment

The combustion demonstration with Red Phosphorus 50 g is usually set up with:

• Deflagrating Spoon — holds a small portion in the flame and inside the gas jar.
• Gas Jar, Glass — contains the oxygen in which the phosphorus burns.
• Gas Jar Cover — keeps the white oxide smoke inside the jar after burning.
• Phosphorus Oxide (V) — the combustion product, for studying its reaction with water directly.
• Blue Litmus Paper — shows that the solution formed from the oxide is acidic.

Frequently Asked Questions

What is the difference between red and white phosphorus?
Red Phosphorus 50 g contains the red allotrope, which is stable in air, much less toxic and ignites only when heated. White phosphorus is waxy, glows in air, can catch fire on its own and must be stored under water, so the red form is the one used for classroom demonstrations.

Which experiments use Red Phosphorus 50 g?
Red Phosphorus 50 g is used to compare allotropes, to burn a non-metal in oxygen and form phosphorus(V) oxide, and to show that the oxide dissolves in water to give an acidic solution. Teachers also use it to explain how the striking surface of a safety-match box works.

How should Red Phosphorus 50 g be stored?
Store Red Phosphorus 50 g in its closed container in a cool, dry chemical cabinet away from flames, heat and oxidising agents such as chlorates and nitrates. Mixtures with strong oxidisers can ignite or explode on friction, so keep them on separate shelves and follow the MSDS.

What is the shelf life of Red Phosphorus 50 g?
Shelf life depends on the chemical, its grade and storage conditions, so no fixed period is quoted for Red Phosphorus 50 g. Ask us for the expiry date of the batch you are quoted, and keep the lid closed because the powder can slowly absorb moisture from air.

Can Red Phosphorus 50 g be shipped to other countries?
Red Phosphorus 50 g is quoted for customers in India and international markets, but as a flammable solid it has transport restrictions. Tell Jain Scientific Equipments Pvt Ltd (ScienceLab) the destination and quantity when you enquire, and the available shipping route will be confirmed with the quotation.
