Bromine (Water Bromine)
Bromine (Water Bromine) (Product Code: SCI-471/200) is an analytical reagent grade solution of bromine in water used to test for unsaturation, compare the reactivity of the halogens and identify phenols and aromatic amines in school and college chemistry laboratories. Teachers and lab assistants dispense it in small portions for test-tube reactions, and this listing is a 100 ml pack supplied with an MSDS. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, a laboratory chemicals supplier in India.

What Is Bromine Water Used For?
The orange-brown colour of bromine water disappears when it is shaken with an alkene, but stays when it is shaken with an alkane such as cyclohexane in the dark — the standard school test for a carbon–carbon double bond. Phenol and aniline also remove the colour and give a white precipitate, which helps identify them. Added to potassium iodide solution, bromine displaces iodine and turns the liquid brown, showing that bromine is more reactive than iodine.
Bromine vapour irritates the eyes and lungs, so dispense the solution in a fume cupboard while wearing goggles and gloves. The solution slowly loses bromine to the air and weakens, so keep it tightly stoppered in a cool, dark chemistry reagent cabinet, away from metals and reducing agents.
What to Specify When Ordering
- Product code SCI-471/200 and the number of 100 ml packs.
- The bromine concentration your tests require, as the listing does not state it.
- The delivery location, so packing and shipping of the solution can be planned.

Frequently Asked Questions
What is Bromine (Water Bromine) SCI-471/200?
Bromine (Water Bromine) SCI-471/200 is an analytical reagent grade bromine water listed in a 100 ml pack and supplied with an MSDS. The listing does not state the bromine concentration, so ask us for the batch specification if your method needs a particular strength.
How is Bromine (Water Bromine) used to test for alkenes?
Shake a few drops of Bromine (Water Bromine) with the test liquid: an alkene quickly removes the orange-brown colour, while an alkane leaves it unchanged in the dark. Run a control alongside and carry out the test in a fume cupboard.
Why does Bromine (Water Bromine) lose strength?
Bromine (Water Bromine) gradually releases bromine vapour, especially when it is warm, left open or exposed to light, so its colour and reactivity fade. Keep the bottle tightly stoppered in a cool, dark cupboard and check the colour before each practical.
What is the shelf life of Bromine (Water Bromine)?
Shelf life depends on the chemical, its grade and storage conditions; ask us for the expiry date of the batch you are quoted. For Bromine (Water Bromine), closed, cool storage also slows the loss of bromine from the solution.
Who supplies Bromine (Water Bromine)?
Bromine (Water Bromine) is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, Haryana, India, which sources reagents, glassware and safety equipment for school, college and institutional laboratories in India and international markets.
What should a Bromine (Water Bromine) enquiry include?
A Bromine (Water Bromine) enquiry should include the product code SCI-471/200, the number of 100 ml packs, any concentration requirement and the delivery location. Send it through the contact page; bulk and export requests are handled the same way.
