Product Code : SCL-LC-12272
Potassium Metal (SKU SCL-LC-12272) is elemental potassium, K, a highly reactive alkali metal used by trained staff for controlled demonstrations of Group 1 behaviour and for reagent work under a written SOP. Because it is water-reactive and pyrophoric, it is intended only for college and institutional laboratories with hazardous-chemical controls. Science Lab Supplies can quote and dispatch it from Ambala, India, to such laboratories, tender contractors and distributors.
Specifications
Potassium has the symbol K, CAS number 7440-09-7 and an atomic weight of about 39.10 g/mol. It is a strong reducing metal that reacts with water and can ignite in air, so it is supplied under a protective medium or in sealed containment. Purity, piece form, medium and quantity appear on the label and quotation.

Applications and Experiments for Potassium Metal
Potassium sits below sodium in Group 1 and reacts even more vigorously, so a controlled demonstration by trained staff makes the trend in alkali-metal reactivity easy to see. It also supports lessons on reducing behaviour and on storing water-reactive chemicals.
- Class 11 chemistry: the s-block elements, comparing potassium with lithium and sodium down Group 1.
- B.Sc. inorganic chemistry: alkali-metal reactivity, metallic bonding and reducing behaviour.
- Reagent use by trained staff under a written SOP.
- Safety training on pyrophoric and water-reactive substances.
Standard Scope of Supply
The supply is one container of potassium metal per unit, held under a protective medium or sealed containment, with a batch label, hazard marking, the Safety Data Sheet and the dangerous-goods transport documents. Purity and quantity follow your quotation. Shelf life depends on the chemical, its grade and storage conditions; ask us for the expiry date of the batch you are quoted.
Packing, MOQ and Lead Time
Request a quotation for a single container or for several institutional labs; it will give packing, delivery time and price for that quantity and confirm the dangerous-goods packing for this metal. Other reagents and chemistry lab equipment in India can be quoted alongside.
As a registered exporter with an Importer-Exporter Code, Science Lab Supplies can ship to buyers in Malaysia, Peru, Egypt, Iraq, Nigeria and Kenya. Science Lab Supplies is registered for GST (GSTIN 06ADEPJ0574F2ZU). Use the contact page for questions or the enquiry cart for a multi-item request; tender buyers should also read the lab tender page.
Frequently Asked Questions
Why is potassium metal so hazardous?
As a Group 1 alkali metal it gives up its outer electron very easily, so it reacts vigorously with water and is pyrophoric in air. That is why it needs strict dry storage and handling.
What protective medium is the potassium supplied in?
It comes under a protective medium or in sealed containment. The exact medium is stated on the label of your batch, and you can ask us to confirm it before ordering.
Who supplies the Potassium Metal?
Science Lab Supplies quotes it from Ambala, India, as a laboratory chemicals supplier in India for trained college and institutional labs and distributors, stating purity and pack size on each quotation.
What safety controls does potassium metal need?
A written SOP, trained supervision, emergency controls and the current Safety Data Sheet. Keep it in a dry, restricted-access store away from water, acids and oxidisers, and never issue it to students unsupervised.
Related Potassium and Alkali Metal Reagents
Group 1 teaching compares potassium with sodium and with the everyday potassium compounds students meet in other practicals. The four chemicals below, from the same range, fill out that comparison and can be ordered on the same quotation as the metal.
- Sodium Metal in Kerosene Vaseline — the other alkali metal, kept under a protective medium.
- Potassium Hydroxide Flakes — strong alkali for titration and base reactions.
- Potassium Chloride — chloride salt for solution work and chloride-ion teaching.
- Potassium Nitrate — nitrate salt for solubility and crystallisation work.
