Potassium Bromide
Potassium Bromide (Product Code: SCI-473/201) is an analytical reagent grade inorganic salt used as a source of bromide ions in halide tests and halogen displacement experiments, and for pressing sample discs in infrared spectroscopy, in school, college and university laboratories. The 200 g pack serves both qualitative analysis classes and instrumental labs, and it is supplied with an MSDS. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, a lab consumables supplier in India.

What Is Potassium Bromide Used For?
With acidified silver nitrate, a bromide solution gives a cream precipitate of silver bromide that dissolves in concentrated ammonia but not in dilute ammonia, which separates it from chloride and iodide in qualitative analysis. Add chlorine water and the solution turns orange as bromine is displaced, showing that chlorine is the more reactive halogen. These tests make potassium bromide a standard entry in any salt analysis kit a school or college assembles.
In instrumental labs, dry potassium bromide is ground with a little of a solid sample and pressed into a clear disc for infrared spectroscopy, because the salt itself is transparent across the usual infrared range. The salt picks up moisture, which shows up in spectra, so keep the container tightly closed and hold working stock in a desiccator.
What to Specify When Ordering
- Product code SCI-473/201 and the number of 200 g packs.
- Whether the salt is for wet qualitative analysis or for infrared sample discs.
- Any assay requirement beyond analytical reagent grade.
- The delivery location and how many MSDS copies you need.

Frequently Asked Questions
What grade and pack size is Potassium Bromide SCI-473/201?
Potassium Bromide SCI-473/201 is listed as analytical reagent grade in a 200 g pack and is supplied with an MSDS. For assay or a spectroscopic grade specification, ask us before ordering and we will share what the batch documentation states.
How does Potassium Bromide behave in the silver nitrate halide test?
With acidified silver nitrate, a Potassium Bromide solution gives a cream precipitate of silver bromide that dissolves in concentrated ammonia but not in dilute ammonia. This separates bromide from chloride, which gives a white precipitate, and iodide, which gives a yellow one.
Can Potassium Bromide be used for IR sample discs?
Potassium Bromide is the salt commonly used to press sample discs for infrared spectroscopy. The listing states analytical reagent grade, so confirm with us whether the batch suits your spectrometer work, and dry the salt thoroughly before pressing discs.
What is the shelf life of Potassium Bromide?
Shelf life depends on the chemical, its grade and storage conditions, so we do not quote a fixed period for Potassium Bromide. Ask us for the expiry date of the batch you are quoted, and store the salt tightly closed in a dry place.
Who supplies Potassium Bromide SCI-473/201?
Potassium Bromide SCI-473/201 is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, Haryana, India, which sources inorganic salts, reagents and apparatus for teaching and testing laboratories in India and international markets.
What should a Potassium Bromide quotation include?
A Potassium Bromide quotation request should include the product code SCI-473/201, the number of 200 g packs, whether the salt is for wet analysis or infrared work, and the delivery location. Send it through the contact page.
