Bromine Water
-Photoroom (1).png)
Product Code : SCL-LC-12191
Bromine Water (SKU SCL-LC-12191) is an aqueous solution of bromine, Br2, typically reddish-brown, used in chemistry laboratories for qualitative organic tests and halogen chemistry. Teachers and lab technicians use it in Class 11–12 and B.Sc. practicals to show unsaturation by decolourisation, always under supervision because the solution is corrosive, oxidising and volatile. Science Lab Supplies furnishes it from Ambala, India to schools, colleges, analytical labs, tender contractors and distributors.
Specifications
The reagent is bromine dissolved in water; its strength may be saturated, dilute or a stated percentage, and that concentration is printed on the label of the batch you are quoted. The strong reddish-brown colour is what makes disappearance of bromine so easy to see in class.

Applications and Experiments for Bromine Water
Bromine water is the classic reagent for showing that a compound contains a carbon-carbon double bond: the reddish-brown colour disappears as bromine adds across it. Students also see it react with phenol, and teachers use it for halogen displacement and oxidising-agent lessons.
- NCERT Class 11 hydrocarbons: testing alkenes for unsaturation by decolourisation.
- NCERT Class 12 alcohols, phenols and ethers: the bromine water test for phenol.
- B.Sc. organic qualitative analysis of functional groups.
- Halogen chemistry demonstrations under a teacher in a ventilated laboratory.
Standard Scope of Supply
Supply is a tightly closed, compatible bottle of bromine water labelled with batch, concentration and hazard details, with the current Safety Data Sheet and tamper-sealed outer packaging holding the export documents. Test samples such as alkenes or phenol are separate chemicals ordered on their own lines.
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
Any quantity from one bottle can be quoted; the quotation shows packing, delivery time and price, and the packing takes account of the reagent being corrosive and volatile. Halogen salts and other school chemistry lab equipment in India for the same organic practicals may be added to it.
Holding an Importer-Exporter Code as a registered exporter, Science Lab Supplies is able to ship to buyers in Ethiopia, Tanzania, Uganda, the UAE, Saudi Arabia and Oman where transport rules for corrosive liquids allow. Enquiries go through the contact page or the enquiry cart, and the lab tender page explains the process for tenders.
Frequently Asked Questions
How does bromine water show an alkene is present?
When shaken with an alkene, the reddish-brown colour disappears because bromine adds across the double bond. A saturated compound leaves the colour largely unchanged under the same conditions.
Is bromine water dangerous?
Yes. It is corrosive and oxidising and gives off vapour that can damage the eyes, skin and airways. Use it in a fume hood or well-ventilated area with gloves, goggles and a lab coat.
Who supplies the Bromine Water?
It comes from Science Lab Supplies in Ambala, India, which quotes schools, colleges and distributors directly and includes the Safety Data Sheet with every bottle.
How should the bottle be stored?
Tightly closed in a labelled, compatible container with secondary containment, away from heat, sunlight, reducing agents, ammonia, combustible materials and incompatible metals, and never released to drains.
Related Halogen and Organic Test Reagents
Halogen lessons compare bromine with iodine and with the halide salts, and the organic tests need a sample to react with. These four items from the Lab Chemicals range complete those practicals and can be priced with bromine water on one quotation.
- Iodine Crystals — elemental halogen for iodine solutions and starch-iodine tests.
- Potassium Bromide — bromide salt for bromide-ion demonstrations.
- Potassium Iodide — iodide salt for qualitative and iodometric work.
- Carbolic Acid Phenol Crystal — phenol, C6H5OH, for trained organic chemistry work.
