Potassium (Metallic)
Potassium (Metallic) (Product Code: SCI-549/238) is an analytical reagent grade alkali metal used by chemistry teachers to demonstrate the vigorous reaction of Group 1 metals with water in senior school and college laboratories. Because it is so reactive, it is intended for teacher-led demonstrations, and it comes in a 25 g pack with its MSDS. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, which also stocks the chemistry lab equipment needed to handle it safely.

What Is Potassium Metal Used For?
A rice-grain-sized piece of potassium placed on water in a wide glass dish darts across the surface, melts into a silvery ball and ignites the hydrogen it releases with a lilac flame, often ending with a small crackle. Adding a few drops of phenolphthalein beforehand turns the water pink as potassium hydroxide forms, showing that the product is a strong alkali. Set beside calcium and magnesium, the demonstration makes the difference between Group 1 and Group 2 metals hard to forget.
Potassium metal is conventionally kept under dry paraffin oil or another inert liquid because it reacts with air and moisture; ask us how the pack you are quoted is presented. Cut pieces on a dry tile with a knife, blot the oil away with filter paper, use a safety screen and goggles, and never let students handle the metal. Old potassium that has formed a yellow crust can be dangerous to cut and should be disposed of as the MSDS directs.
Supplier
Jain Scientific Equipments Private Limited, trading as ScienceLab, supplies Potassium (Metallic) from Ambala, Haryana, to institutions that run supervised alkali-metal demonstrations. We can include the phenolphthalein, glass dish and eye protection for the demonstration in the same quotation. Find out more on the ScienceLab profile page.
Related Laboratory Equipment
A well-prepared potassium-and-water demonstration normally involves:
- Crystallizers — a wide, shallow glass dish of water in which the metal reacts.
- Phenolphthalein 250 ml — indicator that turns pink as potassium hydroxide forms.
- Protective Glass — wrap-around protective eyewear for the demonstrator.
- Calcium (Metallic) — a less reactive metal to compare in the same lesson.
- Potassium Hydroxide 200g — the alkali produced, which students can test without touching the metal.
The Laboratory Equipment category lists further reagents and safety items.
Frequently Asked Questions
What happens when Potassium (Metallic) is added to water?
Potassium (Metallic) reacts violently with water: it skims across the surface, melts, and ignites the released hydrogen with a lilac flame. The water becomes a potassium hydroxide solution, which turns phenolphthalein pink and shows that an alkali has formed.
Can students handle potassium metal?
No. Potassium (Metallic) should be cut and used only by a trained teacher or technician, behind a safety screen and with eye protection. Students watch from a safe distance and can then test the resulting alkaline solution themselves.
How is potassium metal usually stored?
Potassium (Metallic) is conventionally stored under dry paraffin oil in a sealed container, away from water, acids and heat, in a locked chemical cupboard. Ask us how the pack you are quoted is presented, and follow the MSDS supplied with it.
What grade and quantity does this listing supply?
This listing, SCI-549/238, supplies Potassium (Metallic) of analytical reagent grade in a 25 g pack together with its MSDS. Only small pieces are used for each demonstration, so one pack covers many lessons.
What is the shelf life of Potassium (Metallic)?
Shelf life depends on the chemical, its grade and storage conditions, so we give no fixed figure for Potassium (Metallic). Ask us for the expiry date of the batch you are quoted; metal with a thick yellow crust should be disposed of safely.
Can Potassium (Metallic) be sent to institutions outside India?
Potassium (Metallic) reacts with water and air, so dangerous-goods transport rules apply and not every carrier accepts it. Tell us the country, city and quantity through the contact page and ScienceLab will check which supply route is possible before quoting.
Request a Quote
Ask for a Potassium (Metallic) quotation by giving the number of 25 g packs and your delivery location on the contact page, or save it to the enquiry cart with phenolphthalein and eye protection. We will confirm availability, packing and pricing.
